Beyond Nuclear

Background

Beyond Nuclear is an anti-nuclear advocacy organization that was created in 2007 through a rebranding of the Nuclear Policy Research Institute. The Nuclear Policy Research Institute was founded in 2001 by Helen Caldicott who also worked as Beyond Nuclear’s founding president. ³

Beyond Nuclear was founded in 2007 by Linda Pentz Gunter to advocate for a nuclear weapons ban and for nuclear energy to be phased out and replaced with weather-dependent energy. In 2018, Beyond Nuclear launched Beyond Nuclear International, a website that uses current events to advocate for banning nuclear technology. ¹

Advocacy

Reference Girl

Reference Girl is a program of Beyond Nuclear and Gender and Radiation Impact Project that counters scientific research on health risks associated with nuclear energy production that rely on male test subjects. ⁴ Reference Girl argues that conventional methods for selecting test subjects for testing radiation health impacts are racist, sexist, classist, ageist, patriarchal, and colonialist for disproportionally relying on data for health impacts on younger, white men. It also argues that women and children are “less resistant to radiation exposure,” so a standardized female test subject should be used as opposed to a male. ^{5 6}

Opposition to the Trump Administration

Beyond Nuclear has criticized the Trump administration’s pro-nuclear initiatives, for financing private nuclear energy projects, and for purchasing equity in private companies with public funding. In a November 2025 post, it criticized the funding as “the fed gambling with taxpayer dollars for government equity shares in a financially shaky nuclear industry” and is “a serious conflict of interest for the independent federal regulatory oversight.” ⁷

In November 2025, Beyond Nuclear published a letter written to the U.S. Nuclear Regulatory Commission (NRC), U.S. Department of Health and Human Services (HHS) Secretary Robert F. Kennedy Jr., Surgeon General Denise Hinton, and several other Trump administration officials condemning a series of executive orders from President Donald Trump. It opposed President Trump’s directive for the NRC to “reconsider” its use of the linear no-threshold (LNT) model, which is based on the idea that there is no safe threshold for radiation exposure. ²

Leadership

Helen Caldicott is the founder of the Nuclear Policy Research Institute, the predecessor to Beyond Nuclear, and she also founded the anti-nuclear groups Women’s Action for New Directions (Women’s Action for Nuclear Disarmament) and Standing for Truth About Radiation (STAR). She was the founding president of Physicians for Social Responsibility and a member of International Physicians for the Prevention of Nuclear War. Caldicott is also the author of the books Nuclear Madness, Nuclear Power is not the Answer, A Desperate Passion, War in Heaven, and Sleepwalking to Armageddon. ³
