Haw. Code R. § 11-45-40

Current through November, 2024
Section 11-45-40 - Occupational dose limits for adults
(a) The licensee shall control the occupational dose to individual adults, except for planned special exposures, to the following dose limits:
(1) An annual limit, which is the more restrictive of:
(A) The total effective dose equivalent being equal to five rems (0.05 sievert); or
(B) The sum of the deep dose equivalent and the committed dose equivalent to any individual organ or tissue other than the lens of the eye being equal to fifty rems (0.50 sievert).
(2) The annual limits to the lens of the eye, to the skin, and to the extremities which are:
(A) An eye dose equivalent of fifteen rems (0.15 sievert), and
(B) A shallow dose equivalent of fifty rems (0.50 sievert) to the skin or to any extremity.
(b) Doses received in excess of the annual limits, including doses received during accidents, emergencies, and planned special exposures, shall be subtracted from the limits for planned special exposures that the individual may receive during the current year and during the individual's lifetime.
(c) The assigned deep dose equivalent and shallow dose equivalent shall be for the portion of the body receiving the highest exposure determined as follows:.
(1) The deep dose equivalent, eye dose equivalent and shallow dose equivalent may be assessed from surveys or other radiation measurements for the purpose of demonstrating compliance with the occupational dose limits, if the individual monitoring device was not in the region of highest potential exposure, or the results of individual monitoring are unavailable.
(2) Reserved.
(d) Derived air concentration (DAC) and annual limit on intake (ALI) values are presented in Table I of Appendix B and may be used to determine the individual's dose and to demonstrate compliance with the occupational dose limits.
(e) Notwithstanding the annual dose limits, the licensee shall limit the soluble uranium intake by an individual to ten milligrams in a week in consideration of chemical toxicity. See footnote 3 of Appendix B.
(f) The licensee shall reduce the dose that an individual may be allowed to receive in the current year by the amount of occupational dose received while employed by any other person.
(g) Appendix B to Part D of the Conference of Radiation Control Program Directors, Inc. Suggested State Regulations for Control of Radiation, Volume I, December 1995 Edition, entitled, "Annual Limits on Intake (ALI) and Derived Air Concentrations (DAC) of Radionuclides for Occupational Exposure; Effluent Concentrations; Concentrations for Release to Sanitary Sewerage", is made a part of this section and is available from the department.
