Employees are required to wear dosimeters unless an employer has demonstrated and documented that annual occupational exposure to radiation is less than 10% of 5 rems (0.05Sv). To determine annual occupational radiation exposure, a dentist can hire a health physicist to calculate it or dental staff can wear dosimeters for a period to calculate annual exposure.
Annual occupational radiation exposure should be reevaluated from time to time, especially after new equipment is installed or the facility is remodeled. Documentation of radiation monitoring must be made available to radiation inspectors upon request. Documentation should include type of monitoring device, exchange interval and instructions provided to employees.
Individuals utilizing portable hand-held X-ray systems are required to wear dosimeters, with the exception of users of Aribex Nomad, Aribex Nomad Pro, Nomad Pro2, Aribex Nomad eXaminer and Nomad 75kV. Users of portable hand-held X-ray systems are required to comply with Jan. 26, 2016, CDPH "Amended Exemption to California Code of Regulations Title 17, Section 30311 (6)(4), 30314(0)(5) and 30314(6)(1)."
Reports of occupational radiation exposure should be provided to employees. If an employee is occupationally exposed to radiation at other employers' sites, each employer is responsible for ensuring that the total annual occupational dose to the employee does exceed 5 rems (0.05mSv). A log and form to assist employers with this task is available.
