Moving past Sayre’s Law on low-dose radiation
Craig Piercycpiercy@ans.org
So, President Trump has just kicked the low-dose radiation hornets’ nest.
Specifically, his recently signed executive order “Ordering the Reform of the Nuclear Regulatory Commission” calls for the NRC to “reconsider reliance” on the linear no-threshold (LNT) theory and the ALARA (as low as reasonably achievable) standard for radiation protection.
This directive will certainly reignite a vociferous debate within the radiation research community over the continued efficacy of using LNT as the basis for protecting the public and the environment, a community that has been wracked with controversy on this matter for the last few years.
I must admit that whenever the low-dose issue comes up, my first thoughts always go to Sayre’s Law.
