6) If leakage of a test source is indicated, the immediate area in which the test source has been used or stored should be checked for contamination. Shielding of sources while in storage: c. 1) Radioactive test sources, as packed in their shipping containers, are taken to an area previously checked and found to have a background not exceeding 1 mr/hr. Using a calibrated meter, determine the maximum dose rate at the surface of each container. 2) The dose rate at the surface of the outer container shall not exceed 200 mr/hr. The dose rate 1 meter from the surface shall not exceed 10 mr/hr. 3) If either of the above requirements is exceeded, it is an indication of faulty or insufficient shielding. The items must be repacked, using additional shielding or less items per container. After repacking, the shielding test must be repeated. Records of results will be maintained by the RPO using the Army Functional Filing d. System, A source wipe test label will be used on the source assembly or on the source container to readily indicate wipe test dates. The following information will be incorporated on the label: é, Source Wipe Test Date Type Activity Date Serial No. Model Due Date By Ds By (orgn) Safety Precautions: (person) In addition to the standard precautions for handling radioactive material, the following are extremely important: a. Wear surgical type rubber gloves when handling the source. Do not handle the source except with tongs or forceps. Exercise extreme care to avoid dropping the source as this may cause microscopic flaking of the radioactive deposit or other damage. b, Do not touch the active surface of a test source. Cc. Wear a film badge. d. Wash hands thoroughly after handling sources, e. Do not eat, drink, or smoke in a storage area containing radioactive material. All personnel participating in the surveillance testing of radioactive material must be monitored for contamination before leaving the area or before eating, drinking or smoking. A-18-4
