The licensee, certificate holder, and applicant for a CoC shall carry out a comprehensive system of planned and periodic audits to verify compliance with all aspects of the quality assurance program and to determine the effectiveness of the program. The audits must be performed in accordance with written procedures or checklists by appropriately trained personnel not having direct responsibilities in the areas being audited. Audited results must be documented and reviewed by management having responsibility in the area audited. Followup action, including reaudit of deficient areas, must be taken where indicated.
Sec. Appendix A to Part 71--Determination of A1 and
A2
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 Terabecquerel values are the regulatory standard. The curie values are for information only and are not intended to be the regulatory standard. Where values of A1 and 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 Table A-3 may be used. Otherwise, the licensee shall obtain prior Commission 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 Table A-3 may be used. Otherwise, the licensee shall obtain prior Commission 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 shall submit requests for prior approval, described under paragraphs II.a. and II.b. of this Appendix, to the Commission, in accordance with Sec. 71.1 of this part.
III. In the calculations of A1 and A2 for a radionuclide not in Table A-1, a single radioactive decay chain, in which radionuclides are present in their naturally occurring proportions, and in which no daughter radionuclide has a half-life either longer than 10 days, or longer than that of the parent radionuclide, shall be considered as a single radionuclide, and the activity to be taken into account, and the A1 and A2 value to be applied, shall be those corresponding to the parent radionuclide of that chain. In the case of radioactive decay chains in which 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 shall be considered as mixtures of different radionuclides.
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:[GRAPHIC] [TIFF OMITTED] TR26JA04.014 where B(i) is the activity of radionuclide I, 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 as follows: [Sigma]B(i)/A2 (i) <=1 where B(i) is the activity of radionuclide i, and A2(i) is
the A2 value for radionuclide i.
c. Alternatively, the A1 value for mixtures of special form material may be determined as follows:[GRAPHIC] [TIFF OMITTED] TR26JA04.016 where f(i) is the fraction of activity for radionuclide I in the
mixture, and A1(i) is the appropriate A1
value for radionuclide I.
d. Alternatively, the A2 value for mixtures of normal form material may be determined as follows:[GRAPHIC] [TIFF OMITTED] TR26JA04.017 where f(i) is the fraction of activity for radionuclide I in the
mixture, and A2(i) is the appropriate A2
value for radionuclide I.
e. The exempt activity concentration for mixtures of nuclides may be determined as follows:[GRAPHIC] [TIFF OMITTED] TR26JA04.018 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.
f. The activity limit for an exempt consignment for mixtures of radionuclides may be determined as follows: [GRAPHIC] [TIFF OMITTED] TR26JA04.019 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.
V. 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.
