DHS 157.06(1)(1) Records. A licensee or registrant shall maintain records showing the receipt, transfer and disposal of all sources of radiation until the department terminates the license or registration authorizing possession of the device or material, and for 3 years following transfer or disposal of the device or material. DHS 157.06 NoteNote: Additional record requirements are specified elsewhere in this chapter.
DHS 157.06(2)(a)(a) A licensee or registrant shall afford the department at all reasonable times opportunity to inspect sources of radiation, packaging and the premises and facilities on which the sources of radiation are used or stored and consult with workers. DHS 157.06(2)(b)(b) Each licensee and registrant shall make available to the department for inspection, upon reasonable notice, records maintained under this chapter. DHS 157.06(2)(c)(c) The department shall provide official notification in writing of the inspection findings, including any notice of violation, to the licensee or registrant. DHS 157.06(3)(3) Tests. A licensee or registrant shall perform upon instructions from the department, or shall permit the department to perform, such reasonable tests as the department deems appropriate or necessary including tests of any of the following: DHS 157.06(3)(d)(d) Other equipment and devices used with utilization or storage of licensed or registered sources of radiation. DHS 157.06(4)(a)(a) The unit of exposure is the coulomb per kilogram of air. One roentgen is equal to 2.58E-4 coulomb per kilogram of air. DHS 157.06(4)(b)1.1. Gray is the SI unit of absorbed dose. One gray is equal to an absorbed dose of one joule per kilogram (100 rad). DHS 157.06(4)(b)2.2. Rad is the special unit of absorbed dose. One rad is equal to an absorbed dose of 100 erg per gram or 0.01 joule per kilogram. DHS 157.06(4)(b)3.3. Rem is the special unit of any of the quantities expressed as dose equivalent. The dose equivalent in rem is equal to the absorbed dose in rad multiplied by the quality factor. DHS 157.06 NoteNote: 0.01 sievert equals one rem.
DHS 157.06(4)(b)4.4. Sievert is the SI unit of any of the quantities expressed as dose equivalent. The dose equivalent in sievert is equal to the absorbed dose in gray multiplied by the quality factor. DHS 157.06 NoteNote: One sievert equals 100 rem.
DHS 157.06(4)(c)(c) The quality factors for converting absorbed dose to dose equivalent are shown in Table DHS 157.06A. DHS 157.06 NoteNote: Absorbed dose in gray equal to one Sv or the absorbed dose in rad equal to one rem.
DHS 157.06(4)(d)(d) If it is more convenient to measure the neutron fluence rate than to determine the neutron dose equivalent rate in sievert per hour or rem per hour, as provided in par. (c), 0.01 Sv (1 rem) of neutron radiation of unknown energies may be assumed to result from a total fluence of 25 million neutrons per square centimeter incident upon the body. If sufficient information exists to estimate the approximate energy distribution of the neutrons, a licensee or registrant may use the fluence rate per unit dose equivalent or the appropriate Q value from Table DHS 157.06B to convert a measured tissue dose in gray or rad to dose equivalent in sievert or rem.

DHS 157.06 Noteb Monoenergetic neutrons incident normally on a 30-centimeter diameter cylinder tissue-equivalent phantom.
DHS 157.06(5)(5) Units of activity. For purposes of this chapter, activity is expressed in the SI unit of becquerel or in the special unit of curie, or their multiples, or disintegrations or transformations per unit of time. One becquerel = one disintegration or transformation per second. One curie = 3.7E+10 disintegrations or transformations per second = 3.7E+10 becquerel = 2.22E+12 disintegrations or transformations per minute. DHS 157.06 HistoryHistory: CR 01-108: cr.
