A closer look at NRC’s proposed rule eliminating ALARA
On July 1, the Nuclear Regulatory Commission proposed removing the “as low as reasonably achievable” (ALARA) principle from its radiation protection regulations and replacing it with a graded approach. The agency also proposed increases to effluent dose limits and adjusting how it handles allowances for exceeding dose limits.
