Current through Register Vol. 24-14, July 15, 2024
(1)
				Each licensee or registrant shall make and retain records of activities,
				program reviews, measurements, and calculations which may be necessary to
				determine the extent of occupational and public exposure from sources of
				radiation under the control of the licensee or registrant.
(2) Each record required by this section
				shall be legible throughout the specified retention period.
(3) Each licensee or registrant shall use the
				SI units: Becquerel, gray, sievert and coulomb per kilogram, or the special
				units: Curie, rad, rem, and roentgen, including multiples and subdivisions, and
				shall clearly indicate the units of all quantities on records required by these
				regulations.
(4) The licensee or
				registrant shall make a clear distinction among the quantities entered on the
				records required by these regulations such as, total effective dose equivalent,
				total organ dose equivalent, shallow dose equivalent, lens dose equivalent,
				deep dose equivalent, or committed effective dose equivalent.
(5) Records which must be maintained under
				this part shall be the original or a reproduced copy or microform if such
				reproduced copy or microform is duly authenticated by authorized personnel and
				the microform is capable of producing a clear and legible copy after storage
				for the period specified by department regulations. The record may also be
				stored in electronic media with the capability for producing legible, accurate,
				and complete records during the required retention period. Electronic media
				data storage systems shall incorporate standard or universally recognized
				security measures. Records, such as letters, drawings, and specifications,

				RHF-4 or RHF-4A, or equivalent;
(b)
				Records on department Form RHF-5 or RHF-5A, or equivalent, of doses received by
				all individuals for whom monitoring was required pursuant to WAC 246-221-090 and 246-221-100;
(c) Records of
				doses received during planned special exposures, accidents, and emergency
				conditions;
(d) The specific
				information used to calculate the committed effective dose equivalent pursuant

(e) Records
				of the results of surveys to determine the dose from external sources of
				radiation used, in the absence of or in combination with individual monitoring
				data, in the assessment of individual dose equivalents;
(f) Records of the results of measurements
				and calculations used to determine individual intakes of radioactive material
				and used in the assessment of internal dose;
(g) Records showing the results of air
				sampling, surveys, and bioassays required pursuant to WAC 246-221-117 (1)(b)(i)
				and (ii);
(h) Records of the
				results of measurements and calculations used to evaluate the release of
