People in Florida could soon be driving on roads that include radioactive materials. Lawmakers have approved a bill that would order the Florida Transportation Department to conduct demonstration projects using a radioactive waste material from the fertilizer industry in paving roads. Conservation groups are urging Governor Ron DeSantis to veto the bill. They say the radioactive waste known as phosphogypsum [[ fos-foh-JIP-sum ]] would hurt water quality and put road construction crews a higher risk of cancer. The EPA regulates the material so any plans to use it in roads would require a review by the federal agency.
