A bomb squad was called to a home in Massachusetts after radioactive and explosive materials were discovered inside the property following the death of a chemist who had lived there. The find prompted a hazardous materials response, reflecting the risks posed by unregulated chemical stockpiles kept in private residences and the challenges authorities face when such materials are only discovered after a resident's death.

The full details of the response, including the specific location, the exact substances found, and how authorities are handling the clean-up, were not available in the source material provided. As is typical in such cases, specialist teams would be expected to assess and safely remove any dangerous materials before the property could be declared safe.
