Announcing cancellation of facility tours: RERF has decided to not accept reservations for RERF facility tours during the months of February and March, given the rise in number of coronavirus cases. This policy was put in place out of utmost concern for the safety of RERF’s study participants. How this matter will be handled starting in April is as yet undecided. We ask for understanding of our stance regarding this important issue. – Radiation Effects Research Foundation (RERF)
