Iowa Administrative Code › Agency 641 - Public Health Department › Chapter 40 - Standards for Protection Against Radiation › Rule 641-40.1 - Purpose and Scope

Current through Register Vol. 47, No. 3, July 24, 2024
(1) This
			 chapter establishes standards for protection against ionizing radiation
			 resulting from activities conducted pursuant to licenses or registrations
			 issued by the agency. These rules are issued pursuant to the authority in Iowa
			 Code sections
			 136C.3 and
			 136C.4.
(2) The requirements of this chapter are
			 designed to control the receipt, possession, use, transfer, and disposal of
			 sources of radiation by any licensee or registrant so the total dose to an
			 individual, including doses resulting from all sources of radiation other than
			 background radiation, does not exceed the standards for protection against
			 radiation prescribed in this chapter. However, nothing in this chapter shall be
			 construed as limiting actions that may be necessary to protect health and
			 safety.
(3) In addition to
			 complying with the requirements set forth in this chapter, every reasonable
			 effort should be made to maintain radiation exposures and releases of
			 radioactive material in effluents to unrestricted areas as low as is reasonably
			 achievable (ALARA). The term "as low as is reasonably achievable" means as low
			 as is reasonably achievable taking into account the state of technology and the
			 economics of improvements in relation to benefits to the public health and
			 safety, other societal and socioeconomic considerations, and in relation to the
			 utilization of ionizing radiation in the public interest.
(4) Except as specifically provided in other
			 parts of these rules, this chapter applies to persons licensed or registered by
			 the agency to receive, possess, use, transfer, or dispose of sources of
			 radiation. The limits in this chapter do not apply to doses due to background
			 radiation, to exposure of patients to radiation for the purpose of medical
			 diagnosis or therapy, or to voluntary participation in medical research
			 programs.
(5) All references to any
			 Code of Federal Regulations (CFR) in this chapter are those in effect as of
			 July 22, 2020.
(6) The provisions
			 of Chapter 40 are in addition to, and not in substitution for, any other
			 applicable portions of 641-Chapters 38 to 45.

(1) Any existing
			 license or registration condition that is more restrictive than this chapter
			 remains in force until there is an amendment or renewal of the license or
			 registration.
(2) If a license or
			 registration condition exempts a licensee or registrant from a provision of
			 this chapter in effect on or before January 1, 1994, it also exempts the
			 licensee or registrant from the corresponding provision of this
			 chapter.
(3) If a license or
			 registration condition cites provisions of this chapter in effect prior to
			 January 1, 1994, which do not correspond to any provisions of this chapter, the
			 license or registration condition remains in force until there is an amendment
			 or renewal of the license or registration that modifies or removes this
			 condition.

Current through Register Vol. 47, No. 3, July 24, 2024
(1) Each licensee or registrant shall
			 develop, document, and implement a radiation protection program sufficient to
			 ensure compliance with the provisions of this chapter. See 40.81(136C) for
			 record-keeping requirements relating to these programs.
(2) The licensee or registrant shall use, to
			 the extent practical, procedures and engineering controls based upon sound
			 radiation protection principles to achieve occupational doses and public doses
			 that are as low as is reasonably achievable (ALARA).
(3) The licensee or registrant shall, at
			 intervals not to exceed 12 months, review the radiation protection program
			 content and implementation.
(4) To
			 implement the ALARA requirements of 40.10(2), and notwithstanding the
			 requirements in
			 641-40.26
			 (136C), a constraint on air emissions of radioactive material to the
			 environment, excluding radon-222 and its daughters, shall be established by
			 licensees such that the individual member of the public likely to receive the
			 highest dose will not be expected to receive a total effective dose equivalent
			 in excess of 10 mrem (0.1 mSv) per year from these emissions. If a licensee
			 subject to this requirement exceeds this dose constraint, the licensee shall
			 report the exceedance as provided in
			 641-40.97
			 (136C) and promptly take appropriate corrective action to ensure against
			 recurrence.

Current through Register Vol. 47, No. 3, July 24, 2024
(1) If the licensee
			 or registrant is required to monitor pursuant to both 40.37(1) and 40.37(2),
			 the licensee or registrant shall demonstrate compliance with the dose limits by
			 summing external and internal doses. If the licensee or registrant is required
			 to monitor only pursuant to 40.37(1), or only pursuant to 40.37(2), then
			 summation is not required to demonstrate compliance with the dose limits. The
			 licensee or registrant may demonstrate compliance with the requirements for
			 summation of external and internal doses pursuant to 40.16(2), 40.16(3) and
			 40.16(4). The dose equivalents for the lens of the eye, the skin, and the
			 extremities are not included in the summation, but are subject to separate
			 limits.
(2) Intake by inhalation.
			 If the only intake of radionuclides is by inhalation, the total effective dose
			 equivalent limit is not exceeded if the sum of the deep dose equivalent divided
			 by the total effective dose equivalent limit, and one of the following, does
			 not exceed unity:
a. The sum of the fractions
			 of the inhalation ALI for each radionuclide, or
b. The total number of derived air
			 concentration-hours (DAC-hours) for all radionuclides divided by 2,000,
			 or
c. The sum of the calculated
			 committed effective dose equivalents to all significantly irradiated organs or
			 tissues (T) calculated from bioassay data using appropriate biological models
			 and expressed as a fraction of the annual limit. For purposes of this
			 requirement, an organ or tissue is deemed to be significantly irradiated if,
			 for that organ or tissue, the product of the weighting factors, wj, and the
			 committed dose equivalent, HT50,
			 per unit intake is greater than 10 percent of the maximum weighted value of
			 H50, that is,
			 wxHT50, per unit intake for any
			 organ or tissue.
