A Florida company, Mosaic Fertilizer, received approval from the Environmental Protection Agency to construct a test road using phosphogypsum, a radioactive material, on its private property. This decision, described as "mind-boggling" by environmentalists, revives debates on the safety of using such materials for infrastructure, previously restricted by the Clean Air Act. Mosaic posits that incorporating phosphogypsum into roads may be safer than exposing it in piles, though concerns for construction workers' safety persist. The experimental road may set a precedent for future projects, sparking controversy about public health risks and environmental impacts.
