Tuesday, September 16, 2025 – Tribal advocates sound the alarm over radioactive exposure

The advocacy group, Tewa Women United, is warning nearby Pueblo citizens and other local residents about Los Alamos National Laboratory (LANL) in New Mexico releasing gas containing the weak radioactive substance, tritium. The group says, despite assurances by lab experts and regulators that the substance is safe in relatively small doses, it is a dangerous substance and could pose a threat to pregnant women and others. Tritium is a naturally occuring substance, but is also produced in quantities during nuclear power generation and is a key component in nuclear weapons. LANL says it is forced to release the radioactive gas because the containers they’ve been in for decades pose a risk. We’ll discuss what tritium does and whatever threat, if any, it poses.
