Each sealed source other than those exempt by size or specific regulation must be swipe-tested for leakage at not greater than 6 month intervals except for plated alpha sources which will be swipe tested on a quarterly basis. The 6 month swipe tests will be carried out on or about April 1 and October 1 of each year. If a newly received sealed source does not have a leak test certificate from a transferor indicating that a leak test has been made within six months prior to the transfer, it shall not be placed into use until tested. If the sample indicates a contamination activity greater than 0.005 microcuries, the source is to be withdrawn from use and the RSO notified immediately. Responsibility of the School Director or Department Head See the Responsibility of the School Director of Department Head segment of Unsealed Radioisotopes above.
Typical examples are x-ray equipment, particle accelerators and electron microscopes.
The Committee must approve the person who is to be responsible for the supervision of the operation and manipulation of each item of equipment. This person shall be considered responsible for all operations and manipulations unless the Committee is notified to the contrary in writing. The Committee may require that a log of the operations and manipulations be kept and that this log be subject to the inspection of the Committee or its agent. In the event of any violation of these practices, the Committee may demand cessation of the operations. Resumption of manipulation by the user takes place only by the consent of the Committee or its agent.
