Ventura County has set up radiation air monitors as the Sandy Fire approaches the Santa Susana Field Laboratory (SSFL), a former nuclear reactor and rocket testing site. The blaze, which began Monday, has grown to within roughly a quarter-mile of the facility, prompting at least one family to evacuate.

Firefighters have increased their response as the wildfire continues to expand near the contaminated site, where nuclear research once took place. The proximity raises concerns about potential airborne release of radioactive materials, though officials have not confirmed any detected radiation leaks.

Air monitoring aims to detect any hazardous particles that could be lofted by the flames or smoke. The SSFL has a history of contamination from decades of nuclear and rocket testing, making it a focal point for environmental safety during wildfire events.

The incident highlights the intersection of wildfire risks and legacy nuclear sites in drought-prone California. Climate-driven fire seasons are intensifying, increasing the vulnerability of facilities with lingering toxic or radioactive hazards.

Joan Fidler, a local environmental activist, warned that even small increases in radiation could pose health risks to nearby communities, though current data shows no immediate danger.
