1 Soluble (S); Insoluble (I).

2 "Sub" means that values given are for submersion in a semispherical infinite cloud of airborne material.

NOTE: In any case where there is a mixture in air or water of more than one radionuclide, the limiting values for purposes of this Appendix should be determined as follows:

1. If the identity and concentration of each radionuclide in the mixture are known, the limiting values should be derived as follows: Determine, for each radionuclide in the mixture, the ratio between the quantity present in the mixture and the limit otherwise estabfished in Appendix B for the specific radionuclide when not in a mixture. The sum of such ratios for all the radionuclides in the mixture may not exceed "1" (i.e., "unity").

EXAMPLE: If radionuclides A, B, and C are present in concentrations CA, CB, and Cc, and if the applicable MPC's, are MPCA, and MPCB, and MPCC respectively, then the concentrations shall be limited so that the following relationship exists:

2. If either the identity or the concentration of any radionuclide in the mixture is not known, the limiting values for purposes of Appendix B shall be:

a. For purposes of Table I, Col. 1-6X10-18
b. For purposes of Table I, Col. 2-4X10-7
c. For purposes of Table II, Col. 1-2X10-14
d. For purposes of Table II, Col. 2-3X10-8

3. If any of the conditions specified below are met, the corresponding values specified below may be used in lieu of those specified in paragraph 2 above.

a. If the identity of each radionuclide in the mixture is known but the concentration of one or more of the radionuclides in the mixture is not known the concentration limit for the mixture is the limit specified in Appendix "B" for the radionuclide in the mixture having the lowest concentration limit; or

b. If the identity of each radionuclide in the mixture is not known, but it is known that certain radionuclides specified in Appendix "B" are not present in the mixture, the concentration limit for the mixture is the lowest concentration limit specified in Appendix "B" for any radionuclide which is not known to be absent from the mixture; or

GENERAL PROVISIONS
Purpose.

This part establishes procedures and standards for the issuance of an Access Permit to any person subject to this part who requires access to Restricted Data applicable to civil uses of atomic energy for use in his business, trade or profession; provides for the amendment, renewal, suspension, termination and revocation of an Access Permit; and specifies the terms and conditions under which the Commission will issue the Permit.

(c) "Category" means a category of Restricted Data designated in Appendix "A" to the regulations in this part.

(d) "Commission" means the Atomic Energy Commission or its duly authorized representatives.

(e) "Permittee" means the holder of a permit issued pursuant to the regulations in this part.

(f) "Person" means (1) any individual, corporation, partnership, firm, association, trust, estate, public or private

institution, group, Government agency other than the Commission, any state or any political subdivision of, or any political entity within a state, or other entity; and (2) any legal successor, representative, agent, or agency of the foregoing.

(g) "Restricted Data" means all data concerning (1) design, manufacture or utilization of atomic weapons; (2) the production of special nuclear material; or (3) the use of special nuclear material in the production of energy, but shall not include data declassified or removed from the Restricted Data category pursuant to section 142 of the Act. § 25.4 Interpretations.

Except as specifically authorized by the Commission in writing, no interpretation of the meaning of the regulations in this part by any officer or employee of the Commission other than a written interpretation by the General Counsel will be recognized to be binding upon the Commission.

§ 25.5 Communications.

Communications concerning rule making, i.e., petition to change Part 25, should be addressed to Secretary, U.S. Atomic Energy Commission, Washington D.C. 20545. All other communications concerning the regulations in this part, and applications filed under them, should be addressed to the Commission Operations Office listed in Appendix "B" of this part responsible for the geographical area in which (a) the applicant's principal place of business is located, or (b) the principal place where the applicant will use the Restricted Data is located. § 25.6 Categories of available information.

For administrative purposes the Commission has categorized Restricted Data which will be made available to permittees in the categories as set forth in Appendix "A" to this part. Top Secret information; information pertaining to the design, manufacture or utilization of atomic weapons; and defense information other than Restricted Data are not included in these categories and will not be made available under this part. § 25.7 Specific waivers.

The Commission may, upon application of any interested party, grant such waivers from the requirements of this part as it determines are authorized by

(a) Any person desiring access to Restricted Data pursuant to this part should submit an application (Form AEC 378), in triplicate, for an access permit to the Commission's Operations Office, listed in Appendix "B" to this part, responsible for the area in which (1) the applicant's principal place of business is located, or (2) the principal place where the applicant will use the Restricted Data is located.

(b) Where an individual desires access to Restricted Data for use in the performance of his duties as an employee, the application for an access permit must be filed in the name of his employer.

(c) Self-employed private consultants, desiring access to Restricted Data, must file the application in their own name for an individual access permit.
