All changes described herein are needed to comply with the requirements of Florida's agreement state compact with the U.S. Nuclear Regulatory Commission (NRC). As an agreement state, Florida's regulations governing the possession and use of radioactive materials must be identical to the NRC's regulations for federal radioactive materials licensees. The proposed rule specifies requirements for registration of general licenses; requirements for manufacturer or distributors of generally licensed devices; changes in the way shallow dose equivalent is calculated; revises the use of individual respiratory protection equipment which limit intake of radioactive materials; regulations of very large sources of radiation used in industrial radiography; requirements for well loggers; increase the controls needed to prevent unauthorized removal of portable gauges containing radioactive materials; and requirements on following the U.S. Department of Transportation regulations specified in 49 Code of Federal Regulations.
