The curie (Ci) values specified are obtained by converting from the Terabecquerel (TBq) figure. The Terabecquerel values are the regulatory standard. The curie values are for information only and are not intended to be the regulatory standard. The curie values are expressed to three significant figures to assure that the difference in the TBq and Ci quantities is one tenth of one percent or less. Where values of A or 1 A are unlimited, it is for radiation control purposes only. For nuclear criticality safety, some 2 materials are subject to controls placed on fissile material. 17A2 For individual radionuclides whose identities are known, but which are: 17A2.1 Not listed in Table 17A1:

(1) The A and A values Table 17A3 may be used.

1 2 (2) Otherwise, the licensee shall obtain prior NRC approval of the A and A values 1 2 for radionuclides not listed in Table 17A1, before shipping the material. The licensee shall submit such request for prior approval to NRC in accordance with 10 CFR 71.1.

17A2.2 Not listed in Table 17A2:

(1) The exempt material activity concentration and exempt consignment activity values contained in Table 17A3 may be used.

(2) Otherwise, the licensee shall obtain prior NRC approval of the exempt material activity concentration and exempt consignment activity values for radionuclides not listed in Table 17A2, before shipping the material. The licensee shall submit such request for prior approval to NRC in accordance with 10 CFR 71.1. 17A3 In the calculations of A and A for a radionuclide not in Table 17A1, a single radioactive decay 1 2 chain, in which radionuclides are present in their naturally occurring proportions, and in which no radioactive decay product nuclide has a half-life either longer than 10 days, or longer than that of the parent nuclide, shall be considered as a single radionuclide, and the activity to be taken into account, and the A or A value to be applied shall be those corresponding to the parent nuclide 1 2 of that chain. In the case of radioactive decay chains in which any radioactive decay product nuclide has a half-life either longer than 10 days, or greater than that of the parent nuclide, the parent and those radioactive decay product nuclides shall be considered as mixtures of different nuclides.

17A4 For mixtures of radionuclides whose identities and respective activities are known, the following conditions apply:

17A4.1 For special form radioactive material, the maximum quantity transported in a Type A package is as follows:

B(i)

  1 i A (i)

1 where B(i) is the activity of radionuclide i, and A (i) is the A value for radionuclide i. 1 1 18 CODE OF COLORADO REGULATIONS 6 CCR 1007-1 Part 17 Hazardous Materials and Waste Management Division 17A4.2 For normal form radioactive material, the maximum quantity transported in a Type A package is as follows:

where B(i) is the activity of radionuclide i, and A (i) is the A value for radionuclide i. 2 2 17A4.3 Alternatively, an A value for mixtures of special form material may be determined as 1 follows:

where f(i) is the fraction of activity of nuclide i in the mixture and A (i) is the appropriate 1 A value for nuclide i.

1 17A4.4 Alternatively, the A value for mixtures of normal form material may be determined as 2 follows:

where f(i) is the fraction of activity of nuclide I in the mixture and A (i) is the appropriate 2 A value for nuclide I.

2 17A4.5 The exempt activity concentration for mixtures of nuclides may be determined as follows: where f(i) is the fraction of activity concentration of radionuclide i in the mixture, and [A] is the activity concentration for exempt material containing radionuclide i. 17A4.6 The activity limit for an exempt consignment for mixtures of radionuclides may be determined as follows:

where f(i) is the fraction of activity of radionuclide i in the mixture, and A is the activity limit for exempt consignments for radionuclide i.

19 CODE OF COLORADO REGULATIONS 6 CCR 1007-1 Part 17 Hazardous Materials and Waste Management Division 17A5 When the identity of each radionuclide is known, but the individual activities of some of the radionuclides are not known, the radionuclides may be grouped and the lowest A or A value, as 1 2 appropriate, for the radionuclides in each group may be used in applying the formulas in 17A4. Groups may be based on the total alpha activity and the total beta/gamma activity when these are known, using the lowest A or A values for the alpha emitters and beta/gamma emitters. 1 2 20 CODE OF COLORADO REGULATIONS 6 CCR 1007-1 Part 17 Hazardous Materials and Waste Management Division TABLE 17A1: A AND A VALUES FOR RADIONUCLIDES 1 2 Symbol of Element and A1 (TBq) A1 (Ci)b A2 (TBq) A2 (Ci).

a A1 and/or A2 values include contributions from daughter nuclides with half-lives less than 10 days. b The values of A1 and A2 in Curies (Ci) are approximate and for information only; the regulatory standard units are Terabecquerels (TBq) (see Appendix 17A – Determination of A1 and A2, Section 17A1) c The quantity may be determined from a measurement of the rate of decay or a measurement of the radiation level at a prescribed distance from the source.

d These values apply only to compounds of uranium that take the chemical form of UF6, UO2F2 and UO2(NO3)2 in both normal and accident conditions of transport.

e These values apply only to compounds of uranium that take the chemical form of UO3, UF4, UCl4, and hexavalent compounds in both normal and accident conditions of transport. f These values apply to all compounds of uranium other than those specified in d and e, above. g These values apply to unirradiated uranium only.

h These values apply to domestic transport only. For international transport, use the values in the table below.
