Project Sunshine

Beginning in 1953, the United States Atomic Energy Commission initiated a classified research program to measure the accumulation of strontium-90 in human bone tissue. Strontium-90 is a radioactive isotope produced by nuclear weapons testing. It behaves chemically like calcium in the body and concentrates in bone. As atmospheric nuclear testing accelerated through the 1950s and early 1960s, the AEC needed to understand how much strontium-90 was accumulating in human populations and what the health consequences might be.

The program required human bone samples. Specifically, it required samples from the most sensitive population: infants and young children, whose rapidly growing bones absorb strontium-90 at higher rates than adult bone. The AEC obtained those samples by arranging with hospitals and medical examiners around the world to collect bone tissue from deceased infants and children during autopsy or routine post-mortem examination. The parents of those children were not told. They did not consent. In many cases they were told nothing had been taken from their children's bodies.

Project Sunshine operated through a network of cooperating institutions in the United States and internationally. In the United States, hospitals and medical examiner offices in multiple cities participated in the collection. In the United Kingdom, the program operated through the Medical Research Council and collected samples from British infants and children. Australian and Canadian institutions also participated. The international scope of the program reflected the AEC's need for samples from populations with varying levels of nuclear fallout exposure to compare strontium-90 accumulation rates across geographic regions.

The program's participants included researchers at universities, government laboratories, and medical institutions. The collection was conducted under the cover of routine pathological examination. Families requesting their children's bodies for burial received them without being informed that bone samples had been removed. In some documented cases, samples were taken from bodies that families had specifically requested be returned intact for religious or cultural reasons.

The AEC's internal communications about the program, portions of which were declassified through the Advisory Committee on Human Radiation Experiments in 1994, describe the collection methodology with a clinical detachment that makes the ethical dimensions of the program difficult to fully absorb. The program was treating the bodies of dead children as research material without the knowledge of their families. The people making those decisions described it in the language of scientific necessity.

The scientific purpose of Project Sunshine was legitimate and the data it produced was used in assessments of nuclear fallout risk that ultimately contributed to arguments for the Partial Nuclear Test Ban Treaty of 1963. Strontium-90 accumulation in children's bones was a genuine public health concern during the period of atmospheric nuclear testing. Understanding the rate of accumulation required the bone samples the program collected.

The scientific legitimacy of the purpose does not address the ethical character of the method. Medical research requiring human tissue samples from deceased individuals is conducted today under consent frameworks that require notification of next of kin and either consent or a formal waiver process. Project Sunshine operated with no such framework. The bodies of dead children were treated as a resource to be used for scientific purposes that the children's families were not told about and did not authorize.

The AEC's internal documents from the period discuss the collection methodology in terms of logistical efficiency. A 1953 document describes the program's goal of obtaining as many samples as possible from as wide a geographic area as possible. The word consent does not appear in the portions of the program's documentation that have been released.

Project Sunshine became public knowledge through the work of the Advisory Committee on Human Radiation Experiments, a body established by President Clinton in 1994 to review the history of government-sponsored radiation research involving human subjects. The ACHRE conducted a comprehensive review of classified records and produced a final report in 1995 that documented Project Sunshine among many other programs involving non-consensual human radiation research.

The ACHRE report described Project Sunshine as a program in which the rights of the deceased and their families were not considered in the design or operation of the research. The committee recommended formal acknowledgment and apology to the families affected. The Clinton administration issued a formal apology for the government's radiation research programs in 1995.

The apology did not identify specific families whose children's remains had been used without consent. The program's records were not complete enough to reconstruct a full list of the children whose remains had been sampled. Many families whose children were included in the program were never specifically notified, because the program's documentation did not preserve identifying information about individual cases in a form that allowed systematic notification.

The Australian dimension of Project Sunshine became a significant political issue in Australia in the 1990s and 2000s as families there learned that samples had been taken from their children. The Australian government conducted its own inquiries into the program's operation within Australian institutions. Those inquiries confirmed that samples had been collected from Australian infants and children through the same non-consensual methodology used in the United States.

The Australian cases attracted particular attention because some of the families who came forward had specifically asked that their children's bodies be returned complete for burial. The documentation showed that samples had been taken regardless. Families who had been told their children were returned intact learned decades later that parts of those children had been retained for research without their knowledge.

The Australian government issued formal apologies to affected families. Compensation programs were established in some jurisdictions. The United Kingdom conducted similar inquiries and found similar practices in British institutions participating in the program. The geographic scope of Project Sunshine's non-consensual tissue collection extended across multiple allied nations and affected an unknown number of families in each.

The US Atomic Energy Commission collected bone samples from deceased infants and children across multiple countries for approximately twenty years without informing their families. The program's scientific purpose was legitimate. Its method was the systematic use of children's bodies as research material without the knowledge or consent of the people who had the right to make that decision. The program was classified. It became public through a 1994 government review of radiation research. Formal apologies were issued. Many affected families were never individually notified because the program's records did not preserve the information required to identify them.
