THORIUM FLUORIDE REGULATIONS Government hazardous materials regulations require companies that deal with radioactive materials to comply with certain restrictions. Among the requirements is the need to obtain a “specific” license and expand radiation safety programs. Guidelines for complying with the 2013 regulations can be found by clicking here for "Guidance for Implementation of the Final Rule - Distribution of Source Material to Exempt Persons and to General Licensees (10 CFR 30, 40, 70, 170 & 171)." MATERION COMPLIANT Materion has addressed the requirements of the regulations and is fully compliant. For technical support in using ThF4 replacement products, please contact us.
