Fees (1) Only a limited number of special calibrations can be undertaken and requests for such should be submitted with full details for consideration. *For current fees, see Appendix C. Fee (*) (*) (*) 204.502 Gamma-ray sources. Radioactive preparations submitted to the Bureau for test are subject to the following conditions: (a) Financial responsibility: The Bureau assumes no responsibility for loss or damage to radioactive preparations while in its possession. The risk should be covered by insurance. (b) Period of measurement: Approximately 10 days are required for measurement of these radioactive preparations. (c) Preparation of specimens: Radioactive preparations submitted for test must be carefully sealed so that there can be no escape of any radioactive material, including any gaseous decay products. The preparations, shielding, and packaging must be free of contamination. Contaminated or leaking preparations cannot be measured and may cause considerable loss of time and damage to laboratory facilities. Preparations must have been sealed for a sufficient time to be substantially in radioactive equilibrium with their decay products when these contribute to the gamma emission (at least 30 days for radium). (d) Packaging for shipment: Regulations of the Interstate Commerce Commission regarding the shipment of radioactive substances by rail must be complied with. These regulations are enforceable by law and prospective shippers of these substances need to be familiar with them. Copies of the regulations can be obtained from the Interstate Commerce Commission, Washington, D.C., 20423. (e) Possession of licensed material: In submitting specimens of cobalt 60 or other licensed source material (except radium, which is not licensed) for calibration, it will be necessary for the submitter to certify that he is duly authorized to possess the material under license by the USAEC, except in the case of individuals residing in a State which has entered into agreement with the USAEC, in which case State regulations are applicable. This certification may be by letter, by a suitable statement on the purchase order covering the calibration fee, or by a clear copy of the submitter's Possession License for the source material. (f) Type of measurements: (1) Radium is calibrated in terms of milligrams of equivalent radium content measured relative to the National Radium Standard through comparison of the gamma radiation from the specimen and the standard. Where the details of encapsulation of the specimen are known, corrections can be made to obtain milligrams of radium content. Cobalt 60 is calibrated in terms of exposure rate, milliroentgens per hour at one meter, based upon comparison with derived standards of cobalt 60. (2) Postal regulations prohibit mailing radioactive materials which require a caution label under ICC regulations. This effectively prohibits placing radioactive preparations in the mail.
