Manufacturing processes can vary by product, application and end use.    


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 has addressed the requirements of the regulations and is fully compliant. For technical support in using ThF4 replacement products, please contact us.
