Radiologic health branch

The Radiologic Health Branch (RHB) licenses users of radioactive material and registers persons possessing generally licensed devices (GLD) containing radioactive materials. Users of radioactive materials include:

Universities and laboratories to conduct scientific research.
Medical and veterinary hospitals and clinics to diagnose and treat human beings and animals.
Nuclear pharmacies that manufacture and distribute radiopharmaceuticals.
Blood banks to sterilize blood.
Companies that provide services, such as sterilization of medical supplies, facility decontamination, and waste processing.
Gauge operators to determine properties of materials, such as moisture, density, thickness, level, and lead content.
Well loggers to conduct oil drilling operations and industrial radiographers to determine construction integrity.

For questions regarding GLDs, send your question to RHBGLLicensingInfo@cdph.ca.gov.

INDUSTRIAL RADIOGRAPHERS: Individuals performing industrial radiography must meet the requirements specified in title 17, California Code of Regulations section 30335.3.
