Massachusetts Man Pleads Guilty to Selling Radioactive Material

Confirmed

Politics Desk

In Short: In addition to the radioactive material charges, Miller pleaded guilty to being a felon in possession of ammunition and explosive materials, and possessing child sexual abuse material.

According to the U.S. Attorney's Office for the District of Massachusetts, Miller launched a business called 'Collect The Periodic Table' to sell samples of chemical elements, including radioactive plutonium and toxic thallium.

The plutonium was imported illegally from Russia and shipped through the U.S. mail, prosecutors said.

In addition to the radioactive material charges, Miller pleaded guilty to being a felon in possession of ammunition and explosive materials, and possessing child sexual abuse material.

A search of Miller's residence in April 2025 revealed numerous potentially hazardous chemicals and radiological substances in his basement, including alkali metals, acids, oxidizers, arsenic, and other substances.

The Massachusetts Department of Environmental Protection expressed concern about the potential impacts on public safety, noting the risks of accidental release, container breakage, and chemical reactions.

Miller's criminal history dates back to at least 2002, when a search of his residence uncovered an apparent rocket launcher, a pipe bomb, and video of Miller setting off improvised explosive devices.

The U.S. Attorney's Office stated that Miller had exhibited a 'long-standing and unlawful obsession with explosives, dangerous chemicals, and radioactive substances.'

Miller's laptop and cellphone also contained child sexual abuse material, which he had accessed as recently as the day before the search warrant.
