All machines, more specifically x-ray tubes, that generate ionizing radiation, including those for either diagnostic or therapeutic purposes, must be registered with the State of California (unless they are located in a Federal facility) within 30 days of acquisition (CCR, Title 17, section 30108). Even if the device is located in a Federal facility, the machine must be registered with Health Physics within 30 days to ensure proper compliance testing is performed. Additionally, if a machine has more than one tube, or if an old tube is replaced with a new tube, the changes need to be registered with Health Physics within 30 days to ensure proper registration with the State of California.
Health Physics performs all required machine registration functions (except for mammography machines). Contact Health Physics at (650) 723-3201.
After the machine is purchased and becomes operable, Health Physics pays biennial fees to the State of California. The machine registration fees are charged back to departments that operate x-ray machines.
To ensure proper registration with the State of California, departments preparing to purchase or acquire radiation-producing machine(s) must provide Health Physics the following information:
- Name of the primary supervisor/operator.
- Description of the machine and its proposed use.
- X-ray Tube Serial number
