"Unrefined and unprocessed ore" means ore in its natural form prior to processing, like grinding, roasting or beneficiating, or refining. Processing does not include sieving or encapsulation of ore or preparation of samples for laboratory analysis.
"Unrestricted area" means an area, to which access is neither limited nor controlled by the licensee or registrant. For purposes of these rules, "uncontrolled area" is an equivalent term.
"Waste" means those low-level radioactive wastes containing radioactive material that are acceptable for disposal in a land disposal facility. For the purposes of this definition, low-level radioactive waste means radioactive waste not classified as high-level radioactive waste, transuranic waste, spent nuclear fuel, or byproduct material as defined in paragraphs (b), (c), and (d) of the definition of byproduct material found in Section R313-12-3.
"Week" means seven consecutive days starting on Sunday.
"Whole body" means, for purposes of external exposure, head, trunk including male gonads, arms above the elbow, or legs above the knees.
"Worker" means an individual engaged in work under a license or registration issued by the Director and controlled by a licensee or registrant, but does not include the licensee or registrant.
"Working level" (WL), means any combination of short-lived radon daughters in one liter of air that will result in the ultimate emission of 1.3 x 105 MeV of potential alpha particle energy. The short-lived radon daughters are, for radon-222: polonium-218, lead-214, bismuth-214, and polonium-214; and for radon 220: polonium-216, lead-212, bismuth-212, and polonium-212.
"Working level month" (WLM), means an exposure to one working level for 170 hours. 2,000 working hours per year divided by 12 months per year is approximately equal to 170 hours per month.
"Year" means the period of time beginning in January used to determine compliance with the provisions of these rules. The licensee or registrant may change the starting date of the year used to determine compliance by the licensee or registrant provided that the decision to make the change is made not later than December 31 of the previous year. If a licensee or registrant changes in a year, the licensee or registrant shall assure that no day is omitted or duplicated in consecutive years.
(1) As used in these rules, the unit of EXPOSURE is the coulomb per kilogram (C per kg). One roentgen is equal to 2.58 x 10-4 coulomb per kilogram of air.
(2) As used in these rules, the units of dose are:
(a) Gray (Gy) is the SI unit of absorbed dose. One gray is equal to an absorbed dose of one joule per kilogram. One gray equals 100 rad.
(b) 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. One rad equals 0.01 Gy.
(c) 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. One rem equals 0.01 Sv.
(d) Sievert (Sv) 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. One Sv equals 100 rem.
(3) As used in these rules, the quality factors for converting absorbed dose to dose equivalent are shown in Table 1.
TABLE 1 Quality Factors and Absorbed Dose Equivalencies Absorbed Dose Equal to a Quality Unit Dose Type of Radiation Factor (Q) Equivalent X, gamma, or beta radiation and 1 1 high-speed electrons Alpha particles, multiple-charged 20 0.05 particles, fission fragments and heavy particles of unknown charge Neutrons of unknown energy 10 0.1 High energy protons 10 0.1 For the column in Table 1 labeled "Absorbed Dose Equal to a Unit Dose Equivalent", the absorbed dose in rad is equal to one rem or the absorbed dose in gray is equal to one Sv.
(4) 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 Subsection R313-12-20(3), 0.01 Sv of neutron radiation of unknown energies may, for purposes of these rules, 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, the licensee or registrant may use the fluence rate per unit dose equivalent or the appropriate Q value from Table 2 to convert a measured tissue dose in gray or rad to dose equivalent in sievert or rem.
TABLE 2 Mean Quality Factors, Q, and Fluence Per Unit Dose Equivalent for Monoenergetic Neutrons Fluence per Fluence per Unit Dose Unit Dose Neutron Quality Equivalent Equivalent Energy Factor neutrons neutrons Mev Q cm-2 rem-1 cm-2 Sv-1 thermal 2.5 x 10-8 2 980 x 106 980 x 108 1 x 10-7 2 980 x 106 980 x 108 1 x 10-6 2 810 x 106 810 x 108 1 x 10-5 2 810 x 106 810 x 108 1 x 10-4 2 840 x 106 840 x 108 1 x 10-3 2 980 x 106 980 x 108 1 x 10-2 2.5 1010 x 106 1010 x 108 1 x 10-1 7.5 170 x 106 170 x 108 5 x 10-1 11 39 x 106 39 x 108 1 11 27 x 106 27 x 108 2.5 9 29 x 106 29 x 108 5 8 23 x 106 23 x 108 7 7 24 x 106 24 x 108 10 6.5 24 x 106 24 x 108 14 7.5 17 x 106 17 x 108 20 8 16 x 106 16 x 108 40 7 14 x 106 14 x 108 60 5.5 16 x 106 16 x 108 1 x 102 4 20 x 106 20 x 108 2 x 102 3.5 19 x 106 19 x 108 3 x 102 3.5 16 x 106 16 x 108 4 x 102 3.5 14 x 106 14 x 108 For the column in Table 2 labeled "Quality Factor", the values of Q are at the point where the dose equivalent is maximum in a 30 cm diameter cylinder tissue-equivalent phantom. For the columns in Table 2 labeled "Fluence per Unit Dose Equivalent", the values are for monoenergetic neutrons incident normally on a 30 cm diameter cylinder tissue equivalent phantom.
For purposes of these rules, activity is expressed in the SI unit of becquerel (Bq), or in the special unit of curie (Ci), or their multiples, or disintegrations or transformations per unit of time.
(1) One becquerel (Bq) equals one disintegration or transformation per second.
(2) One curie (Ci) equals 3.7 x 1010 disintegrations or transformations per second, which equals 3.7 x 1010 becquerel, which equals 2.22 x 1012 disintegrations or transformations per minute.

(b) The licensee who transferred the material shall retain each record of transfer of source or byproduct material until the Director terminates each license that authorizes the activity that is subject to the recordkeeping requirement.
(c) The licensee shall retain each record of disposal of source or byproduct material until the Director terminates each license that authorizes the activity that is subject to the recordkeeping requirement.
(d) If source or byproduct material is combined or mixed with other licensed material and subsequently treated in a manner that makes direct correlation of a receipt record with a transfer, export, or disposition record impossible, the licensee may use evaluative techniques, such as first-in-first-out, to make the records that are required by Section R313-12-51 account for 100 percent of the material received.
(2) The licensee shall retain each record that is required by Section R313-12-51 or by license condition for the period specified by the appropriate rule or license condition. If a retention period is not otherwise specified by rule or license condition, each record must be maintained until the Director terminates the license that authorizes the activity that is subject to the recordkeeping requirement.
(3) A licensee or registrant shall maintain records showing the receipt, transfer, and disposal of all sources of radiation.
(4) Prior to license termination, each licensee authorized to possess radioactive material with a half-life greater than 120 days, in an unsealed form, may forward the following records to the Director:
