Nebraska Administrative Code › Topic - HEALTH AND HUMAN SERVICES SYSTEM › Title 180 - CONTROL OF RADIATION › Chapter 13 - TRANSPORTATION OF RADIOACTIVE MATERIAL › Appendix 13-A - DETERMINATION OF A[1] AND A[2]

Current through June 17, 2024
I. Values of A1 and A2
	 for individual radionuclides, which are the bases for many activity limits
	 elsewhere in these regulations, are given in Table A-1. The curie (Ci) values
	 specified are obtained by converting from the Terabecquerel (TBq) value. The
	 curie values are expressed to three significant figures to assure the
	 difference in the TBq and Ci quantities is one tenth of one percent or less.
	 Where values of A1 or A2 are
	 unlimited, it is for radiation control purposes only. For nuclear criticality
	 safety, some materials are subject to controls placed on fissile
	 material.
II. a. For individual radionuclides whose identities are known, but
	 which are not listed in Table A-1, the A1 and
	 A2 values contained in Appendix 13-A, Table A-3 may be
	 used. Otherwise the licensee must obtain prior Department approval of the
	 A1 and A2 values for
	 radionuclides not listed in Table A-1, before shipping the material.
b. For individual radionuclides whose identities are known, but which
	 are not listed in Table A-2, the exempt material activity concentration and
	 exempt consignment activity values contained in Appendix 13-A, Table A-3 may be
	 used. Otherwise, the licensee must obtain prior Department approval of the
	 exempt material activity concentration and exempt consignment activity values
	 for radionuclides not listed in Table A-2, before shipping the material.
c. The licensee must submit requests for prior approval, described
	 under paragraphs II.a. and II.b. of this Appendix, to the Department, according
	 to 180 NAC 1-012.
III. In the calculations of A1 and
	 A2 for a radionuclide not in Table A-1, a single
	 radioactive decay chain, where radionuclides are present in their naturally
	 occurring proportions, and where no daughter radionuclide has a half-life
	 either longer than 10 days, or longer than that of the parent radionuclide,
	 must be considered as a single radionuclide, and the activity to be taken into
	 account, and the A1 and A2 value
	 to be applied must be those corresponding to the parent nuclide of that chain.
	 In the case of radioactive decay chains where any daughter radionuclide has a
	 half-life either longer than 10 days, or greater than that of the parent
	 radionuclide, the parent and those daughter radionuclides must be considered as
	 mixtures of different nuclides.
IV. For mixtures of radionuclides whose identities and respective
	 activities are known, the following conditions apply:
a. For special form radioactive material, the maximum quantity
	 transported in a Type A package is as follows:

	 view
Where B(i) is the activity of radionuclide i in special form, and
	 A1(i) is the A1 value for
	 radionuclide i.
b. For normal form radioactive material, the maximum quantity
	 transported in a Type A package is a follows:
Click here to
	 view
where B(i) is the activity of radionuclide i in normal form, and
	 A2(i) is the A2 value for
	 radionuclide i.
c. If the package contains both special and normal form radioactive
	 material, the activity that may be transported in a Type A package is as
	 follows:
Click here to
	 view
where B(i) is the activity of radionuclide i as special form
	 radioactive material, A1 (i) is the
	 A1 value for radionuclide i, C(j) is the activity of
	 radionuclide j as normal form radioactive material, and
	 A2 (j) is the A2 value for
	 radionuclide j.
d. Alternatively, the A1 value for mixtures of
	 special form material may be determined as follows:
Click here to
	 view
where f(i) is the fraction of activity for radionuclide i in the
	 mixture, and A2(i) is the appropriate
	 A1 value for radionuclide i.
e. Alternatively, the A2 value for mixtures of
	 normal form material may be determined as follows:
Click here to
	 view
Where f(i) is the fraction of activity of radionuclide i in the
	 mixture, and A2(i) is the appropriate
	 A2 value for radionuclide i.
f. The exempt activity concentration for mixtures of nuclides may be
	 determined as follows:
Click here to
	 view
Where f(i) is the fraction of activity concentration of radionuclide i
	 in the mixture, and [A](i) is the activity concentration for exempt material
	 containing radionuclide i.
g. The activity limit for an exempt consignment for mixtures of
	 radionuclides may be determined as follows:
Click here to
	 view
Where f(i) is the fraction of activity of radionuclide i in the
	 mixture, and A(i) is the activity limit for exempt consignments for
	 radionuclide i.
V. a. 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 A1 or
	 A2 value, as appropriate, for the radionuclides in each
	 group may be used in applying the formulas in paragraph IV. Groups may be based
	 on the total alpha activity and the total beta, gamma activity when these are
	 known, using the lowest A1 or A2
	 values for the alpha emitters and beta, gamma emitters.
b. 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] (activity concentration for exempt material) or A
	 (activity limit for exempt consignment) value, as appropriate, for the
	 radionuclides in each group may be used in applying the formulas in paragraph
	 IV of this appendix. 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, respectively.

(b) The values of A1 and/or
	 A2 in Curies (Ci) are approximate and for information
	 only; the regulatory standard units are Terabecquerel (TBq), (see Appendix 13-A
	 - Determination of A1 and/or A2,
	 Section 1)
(c) The activity of lr-192 in special form 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, UF44
	 UCI4 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 notes (d) and (e) of this table.
(g) These values apply to unirradiated uranium only.
(h) A2 = 0.74 TBq (20 Ci) for Mo-99 for
	 domestic use.
