The Conference of Radiation Control Program Directors (CRCPD) is a nonprofit, nongovernmental professional organization dedicated to radiation protection. CRCPD works to promote consistency in addressing and resolving radiation protection issues, to encourage high standards of quality in radiation protection programs, and to provide leadership in radon safety education.  CRCPD’s primary goal is to assure that radiation exposure to individuals is kept to the lowest practical level, while not restricting its beneficial uses.  CRPCD’s primary membership is made up of radiation professionals in state and local government that regulate the use of radiation sources.

CRCPD currently has three committees pursuing activities related to radon; they are listed below, with links to their Fact Sheets on CRCPD’s website. The members of these committees are directors and staff of state and local radiation control programs; advisors to the committees are individuals outside of state programs who have an interest in CRCPD activities.

  • E-25 Committee on Radon. Addresses all activities relating to the reduction of radon levels in homes and other buildings, works closely with EPA on national efforts to address the radon issues, and provides guidance to states on various radon reduction programs.
  • E-41 - Task Force on Radioactivity in Building Materials. E-41 is tasked with writing a white paper that state radiation control staff and/or state radon contacts could use as guidance when answering citizens questions concerning radioactivity in granite countertops or other building materials and their potential for radon emission or direct radiation exposure; and developing a protocol for state radiation control staff and/or state radon contacts to use in surveying countertops and countertop materials and to determine if they are a significant hazard or if used inside homes they could become a significant hazard to the extent that they should not be used.
  • SR-R Suggested Regulations - Radon. Develops suggested state regulations for Part R (Radon).
