My Family and the Atomic Bomb: The Legacy of “Dirty Harry.”
May 19th, 1953. The horizon softened in the moonless sky an hour before sunrise in Henderson, Nevada, thirteen miles southeast of Las Vegas. Clothes hung limply on the clothesline as my mother, Shirley, awakened my brothers Rick and Steve, helped them dress, and cracked open the back door. Then she picked me up from my crib and followed the boys outside.
She breathed in the coolness of the pre-dawn sky, that first pungent scent of sagebrush, mesquite, and creosote bush floating over the desert, as she inspected the boy’s sneakers and shook them briskly to ensure that a scorpion wasn’t lurking inside. This time, the sneakers were empty. A white delivery truck creaked to a stop in front of the house. The milkman spied us in the back and waved good morning before leaving two half gallons of whole milk, a container of cottage cheese, and two dozen eggs in an insulated metal box by the door. He glanced at his watch, pointed a finger towards the northwest, and drove on.
My mother, petite, with strawberry-blond hair and gray-blue eyes, grew up in the hills of West Virginia in a farmhouse without indoor plumbing. As a nurse, she had worked in the polio wards before meeting my father on a blind date when he was on leave from the Navy shortly before the end of World War II. She was accustomed to heartbreak. When she was only five-years-old, her mother died of heart failure from a diseased heart valve. A toddler brother died from extensive burns when he ventured too close to the hearth and his nightshirt caught fire. A second brother died from a childhood wasting disease, probably from diabetes; a third brother from late complications of polio.
My father Frank joined us, dressed for work, a lit cigarette glowing in the half-darkness, an arm around my mother’s waist. Olive skinned with brown eyes and a neatly trimmed mustache; as a former wrestler, he moved with an athlete’s grace and confidence. The first in his family of Italian immigrants to attend college, he graduated with a degree in chemical engineering. Following his discharge from the Navy, he and my mother moved to Henderson, where he worked at the Montrose Chemical Corporation.
Father glanced at his watch. “Patience, boys. In a moment we’ll see something beyond belief.” And true to his word, shortly after 5 a.m., a blinding light lit up the sky.
At dawn, we gaze in silentbond
a flash of light, and rising cloud
We blink and gasp, the image sears
The hollow blackness cloaks our fears.
As the ground shook, the gray and burgundy mushroom cloud code-named Upshot-Knothole Harry by the Atomic Energy Commission, soared upwards. The 32-kiloton nuclear device—more than twice the power of the atomic bomb dropped over Hiroshima—had been detonated in the Yucca Flat desert basin within the Nevada Test Site less than 75 miles from our home.
Three young brothers catch the sight
of crimson robe in dawn’s half-light.
Trembling sand shifts and shakes.
The boys delight in spectral quake.
On mother’s hip I cling in fright
Restless in the desert blight.
For weeks, the date and time of the upcoming blast had been promoted on TV and radio throughout southern Nevada. In Las Vegas that morning, buildings shook moments after the detonation. Blurry-eyed patrons at the all-night casinos stumbled outside or partied on roof tops while drinking “atomic cocktails.” In one iconic photo, guests in swimsuits at a hotel pool gazed in awe at a burgeoning mushroom cloud on the horizon.
If Las Vegas was Nevada’s nightclub and entertainment epicenter, Henderson was a town grounded in industries such as the Titanium Metals Corporation and Kerr McGee Chemical Corporation. Families like ours regularly witnessed nuclear blasts from our homes on the edge of the desert in a less celebratory, but largely supportive manner. Between January 1951, when the Operation Ranger test series began, and ending with Upshot-Knothole Climax in June of 1953 when we moved east, thirty-one nuclear above ground devices were detonated at the Nevada Test Site, an average of more than one explosion each month. The mushroom clouds were so frequent that on one occasion, my father, an early adopter of home movie camera technology, tried in vain to capture an atomic blast from our backyard with my mother and brothers in the foreground.
My father’s smoke hangs limp in hand
His polished shoes scuff desert sand.
His mind drifts west to atom’s fate
One arm draped round my mother’s waist
North, not east, the toxin’s float
Not here, not now, a wish, a hope
Father left for work. Another day, another atomic bomb. Mother shepherded my brothers inside for an early breakfast. Moments before, just prior to the detonation in Yucca Flat within the Nevada Test Site, the wind whispered north at less than 6 mph. This was as predicted, as the timing of the explosion was planned to coincide with low winds to avoid downwind drift of radiation into Las Vegas or Henderson.
On backyard line, clothes hang like ghosts
Their limbs droop down, of long-dead hosts.
But an unexpected change in wind speed and direction occurred late that morning. Instead of the radiation drifting into the sparsely populated desert of central Nevada (“sparsely populated” included sheep ranches and Native American reservations which were repeatedly radiated during above ground nuclear testing), the surface winds increased to 14 miles per hour, and the direction of the radiation plume shifted ominously eastward.
The breeze shifts, from north to east
A spectral wind from the nuclear beast.
Mother gathers us, we escape inside
The ghosts awaken, and dance on line.
In the days that followed, fallout from Dirty Harry—as the blast was nicknamed in the popular press—was detected at ground level in Colorado and Kansas while another radioactive cloud crossed over Chicago. Upper segments of the blast split off and moved southeast towards El Paso, Texas. Arizona received a heavy dusting. St. George, Utah, 130 miles east of the Nevada Test Site, was hit particularly hard. Pockets of high intensity radiation fell from the sky in upstate New York. In all, measurable fallout occurred in forty-six of the forty-eight contiguous US states. There is general agreement among scientists that Dirty Harry caused the highest amount of radioactive fallout of any nuclear test in the United States, before or since.
Of course, Dirty Harry was only one of the 31 nuclear devices detonated during the years my family lived in Henderson, Nevada, and radioactive iodine-131 only one of over 300 fission products released into the atmosphere. It took another ten years and seventy additional nuclear explosions at the Nevada Nuclear test site before the Limited Test Ban Treaty was signed in Moscow between the United States, Russia, and the United Kingdom.
In the immediate aftermath of Dirty Harry, however, public outcry was muted. There was a high level of trust in the government following World War II and a shared belief that the atomic bombs dropped on Nagasaki and Hiroshima saved tens of thousands, perhaps hundreds of thousands of American and Allied lives by avoiding a land invasion of Japan. The Korean war was raging. The threat of nuclear war with the Soviet Union loomed over the horizon. In the wake of Dirty Harry, a government public relations campaign orchestrated by the Atomic Energy Commission (AEC) minimized the dangers of radiation and played on the patriotism of those downwind of the blast.
Although there was growing concern among individual researchers, a 1955 U.S. News & World Report was typical of many articles in the popular press, concluding that fallout from Big Shot (a later nuclear test) on anyone in the U.S. was equal to that of a luminous-watch dial. It wasn’t until 1977 when Salt Lake City’s Deseret News reported an increased risk of childhood leukemia in Utah counties downwind from the Nevada Test Site that public outcry against the Atomic Energy Commission’s reassurances gained traction. The investigative report by Gordon Eliot White was widely disseminated and public support for nuclear testing wavered. That same year, an initially skeptical Dr. Joseph Lyon at the University of Utah decided to perform his own statistical analysis for southern Utah. The results, published in February 1979 in the prestigious New England Journal of Medicine, confirmed that in children born in southern Utah who were exposed to radiation, the risk of leukemia was 2.4 times higher than in children born in Utah before nuclear testing. The findings added further weight to the link between chronic, even low-dose downwind radiation exposure and subsequent risk of cancer.
And it wasn’t only leukemia. Carl Johnson, a Colorado physician, studied downwind radiation hotspots and gathered detailed information on all forms of cancer. He then compared the rates of malignancy in these communities to cancer rates in communities outside the fallout hotspots. The results were published in the Journal of the American Medical Association in 1983. Johnson confirmed Dr. Lyon’s leukemia data but also determined that the risk of other cancers, including breast, lymphoma, thyroid, melanoma, brain and bone was also increased.
Although above ground nuclear testing had been banned since 1964, pressure mounted on the federal government to recognize the long-term harm to those downwind from the Nevada Test Site. Utah governor, Scott Matheson arranged for congressional hearings in Salt Lake City. In a ground-breaking admission, F. Peter Libassi, representing the United States Public Health Service, acknowledged that the Atomic Energy Commissions’ radiation exposure limits were hopelessly inadequate. According to John Fuller, the author of The Day We Bombed Utah, Libassi agreed with mainstream researchers (many of whom had been sidelined by the Atomic Energy Commission) when he said there were “no safe limits” for radiation exposure.
Former Interior Secretary, Republican Stewart L. Udall of Utah, and Democrat Edward M. Kennedy galvanized bipartisan political support to compensate those affected by nuclear weapons testing. Downwinders, as they came be known, found common cause with military and civilian personnel who were repeatedly exposed at the Nevada Test Site, along with uranium industry workers, many of whom were Native Americans.
Although legislation was introduced in 1979, it would be another eleven years before Congress passed the Radiation Exposure Compensation Act of 1990. The “Downwinder Act,” as it came to be known, provided a flat sum of $50,000 if an applicant had lived in the states of New Mexico and Utah at the time of above ground nuclear testing and developed a listed malignancy. Residents of certain counties in Arizona and Nevada were also included in the settlement, while uranium workers with malignancies received $100,000. Soldiers and observers within the Nevada Test Site at the time of an atmospheric detonation of an atomic weapon were given $75,000 if they developed a radiation-linked cancer.
Despite the proximity of Clark County (which includes Las Vegas and Henderson) to ground zero at the Nevada Test Site, most of the county was excluded from the settlement. It’s unclear exactly why. As a political decision based on flawed scientific data, the exclusion has been contested for decades. Nevada downwinder Linda Chase summed up the feelings of many when she said: “We lived only 70 miles from the test site…I guess they figured the radiation came to the county line, then went around it. The message was clear to me and to all the residents of Clark County and other excluded areas: your sacrifice does not count; you do not matter…”
My mother was the first casualty.
Forty-five years after her exposure to Dirty Harry in 1953, Shirley noticed that her gums bled after brushing her teeth. Tests showed that her white blood cells, platelets, and red blood counts were all well below normal, low enough that she immediately received the first of many blood transfusions. A biopsy of her bone marrow was performed and the result was unequivocal: myelodysplastic syndrome (MD), a leukemic related disease of the bone marrow in which the production of blood is impaired and eventually ceases.
As a physician, I knew that MD primarily occurs in the elderly, and while radiation exposure has been documented as a potent risk factor in Japanese survivors of the atomic bomb, it can also occur in otherwise healthy men and women with no known radiation exposure. Medical treatment in the late 1990’s was rarely effective, and my mother was not a candidate for a bone marrow transplant.
Over the next year, the blood transfusions became more frequent. Her ability to clot worsened and she oozed blood from her gums and bowels day and night. Despite her decline, she kidded about her health: “I’m fine. I have four red blood cells; one goes down each arm and one down each leg.” When her white blood cells were nearly undetectable, she died from a blood infection which spread to her spine.
My brother Steve was next.
Five years after my mother’s illness Steve became fatigued and short of breath. X-rays showed a tumor in the neck, and a grapefruit sized mass in the lung. He was diagnosed with multiple myeloma, another blood cancer commonly seen in radiation survivors. Again, multiple myeloma can occur out of the blue. But two blood cancers in one family? Unlikely.
Steve received a bone marrow transplant and had several good years. He went back to baseball, canoeing, and running, that is, until the myeloma relapsed with a vengeance and he died at age 68. I became convinced that both my mother and Steve’s blood cancers were a delayed effect of radiation exposure and began to unravel more about our family’s years in Henderson, Nevada.
The occurrence of my brother and mother’s cancers was common in long-term radiation survivors. Meticulous long-term follow-up of Hiroshima and Nagasaki residents had already confirmed that the risk of radiation induced cancer persisted more than fifty years after initial exposure. I explored with my brother the possibility of making a claim under the Radiation Exposure Compensation Act, but we learned that by living in Henderson, Nevada at the time of nuclear testing, he was ineligible.
My brother Rick’s leukemia followed several years later.
In 2022, Rick developed shortness of breath and a rapid pulse. He underwent a bone marrow biopsy. The result: acute myelogenous leukemia (AML), one of the most drug resistant and deadly of the leukemias. Now there were three blood malignancies in our family with the common denominator being cumulative, low-level radiation exposure to 31 nuclear blasts 75 miles from our home. Rick and his family steeled themselves to the high likelihood of him passing away within months. Miraculously (and his hematologist and family celebrate this), Rick’s AML responded well to a novel form of chemotherapy, but has relapsed recently. He is alive today.
With my evolving knowledge of just how close we were to above-ground nuclear detonations, even my father’s massive heart attack in 1964 has come into question. Yes, he was a heavy smoker, but a fatal heart attack at age 44? I wondered, could there be a link? Then I came across a British Medical Journal article, Radiation Exposure and Circulatory Disease Risk: Hiroshima and Nagasaki Atomic Bomb Survivor Data, 1950-2003, which documented that even five decades after the bombs were dropped, “the risk of heart disease…account(s) for about one third excess deaths as do cancers among atomic bomb survivors.”
An armchair ethicist might offer the opinion that my brother Steve’s multiple myeloma at age 62, Rick’s leukemia at age 73, and my mother’s myelodysplastic syndrome at age 77 occurred well past middle age and their suffering pales in comparison to the immediate aftermath of survivors of Hiroshima and Nagasaki. The Japanese term, hibakusha, 'a person affected by nuclear exposure', perhaps better captures the health challenges which play out over a lifetime in survivors exposed to low-dose radiation. As of 2025, 99,130 hibakusha were still alive, and many of them continue with radiation related illnesses today.
Following its passage in 1990, the Federal Radiation Exposure Compensation Act dispersed 2.6 billion dollars over the next thirty-four years. Payments were awarded to 26,863 "downwinders” with malignancies, more than 14,000 uranium workers, and thousands of soldiers and observers who were present at the Nevada Test Site close to ground zero. After decades of inaction, the legislation acknowledged the long-term health risks for those in the path of atomic bomb fallout, even hundreds of miles distant from detonation. The act was allowed to expire in 2024, but was restored the next year with the recent reconciliation tax and spending bill. Under the new program, Nevada residents who lived in Las Vegas and Henderson during the years of above ground nuclear testing, were once more excluded from the final bill.
The struggle to have the Federal government accept accountability for the health impacts of above ground nuclear testing during the 1950’s and 60’s continues today. Each year, there are fewer and fewer of us. The health impacts on downwind residents initially reflected ignorance regarding the health risks of cumulative low-dose radiation exposure. But over time, a coverup emerged. As scientific evidence mounted, instead of acknowledging the risks, the Atomic Energy Commission doubled down and conducted publicity campaigns, offered blustery denials, and willfully altered radiation data.
During the Cold War, President Ronald Reagan understood in his negotiations with the Soviet Union, that we should never rely on mere words to avoid nuclear conflict. His slogan, “Trust but Verify” was a cornerstone of Cold War treaties. For 30 years, the Atomic Energy Commission’s insistence that low-level radiation exposure from above ground nuclear testing was safe was based on flawed policy and politics, not science. Ongoing skepticism, public health studies, and eventually, public outrage led to legislation compensating those downwind of nuclear testing.
Today, under the Trump administration, the Nuclear Regulatory Commission (NRC) is proposing that radiation safety laws be significantly weakened. Currently, radioactive materials used by hospitals and nuclear plants must ensure that radiation exposures are kept “as low as reasonably achievable” — the ALARA principle. Whether the exposure is a chest x-ray or a CT scan, the old rule acknowledges that there is no absolutely safe level for radiation exposure. The NRC rule change would abandon that philosophy while keeping a separate standard on maximum radiation exposure. The suggested regulatory change is not science based and ignores the lessons of the past linking cancer risk to cumulative low-dose radiation.
Perhaps Richard L. Miller in his book, Under the Cloud: The Decades of Nuclear Testing, summarized the U.S. governments hardened position (both past and present) best when the Atomic Energy Commission was sued by Utah sheep herders in 1953 over radiation-induced malformations and stillbirths in their herd following exposure to Dirty Harry. The litigants’ lawyer asked the commission a seemingly simple question: “Who has the responsibility for the safety and welfare of persons and property near areas of possible fallout?”
The Atomic Energy Commission’s answer: “It is the responsibility of the heads of families and owners of property to protect the members of their families and their property from possible radioactive fallout.”
In other words, the public would have to protect itself.
My family never had that chance.
