John Dunn, MD, JD:Is it time for the USEPA to reconsider the use of the LNT model in LDDR radiation environments in the regulatory process, especially in the tools it has developed to determine cleanup levels?

It took decades of institutional inertia to arrive at the current irresponsible and unscientific regulatory framework.
