The Ministry of Health (MOH) has made a regulatory amendment to the Healing Arts and Radiation Protection Act (HARPA) to modernize the shielding methodology for x-ray installations.
Dentists applying for an x-ray installation permit should be aware that they have the option of using the existing shielding methodology contained in Appendix 2 of Safety Code 20A or the newly added shielding methodology contained in NCRP Report #147.
