Teenager’s backyard reactor exposes the risks of unsupervised science
SYSK Gets Weird Playlist: The Story of the Nuclear Boy Scout
David Hahn’s story shows how curiosity, access to hazardous materials, and deceptive expertise can turn scientific ambition into a public-safety crisis.
- 1David Hahn used deceptive correspondence and scavenged radioactive materials to pursue a backyard nuclear reactor.
- 2His reactor produced detectable radiation before authorities discovered and removed the contaminated potting shed.
- 3Hahn’s troubled adulthood complicates his legacy as both a warning and an inspiration to young nuclear scientists.
Don't miss
At 17, David Hahn successfully initiated a nuclear chain reaction in the shed and detected radiation from several houses away.
The brief
David Hahn’s childhood fascination with chemistry and radioactivity escalated from homemade experiments to a makeshift laboratory in his mother’s potting shed.
Using a false identity, Hahn corresponded with experts and gathered technical knowledge while collecting americium, uranium, thorium, and other radioactive materials.
At 17, he assembled a tiny breeder reactor and detected radiation from several houses away before dismantling the device.
Authorities discovered the contaminated shed after radioactive materials turned up in Hahn’s car, prompting a costly cleanup and disposal operation.
Hahn’s difficult adulthood and death contrast with Taylor Wilson’s supervised nuclear achievements, leaving a legacy that is cautionary and inspirational.
