All personnel (including barrier monitors) assigned to work in the vicinity of radiation sources or within radiation areas, associated with radiographic operations, are required to wear a primary personnel dosimeter (thermoluminescent dosimeter (TLD)) and two pocket dosimeters. All dosimetry, dosimetry proc edures, and dosimeter exchange f requencies shall conf orm to NAVMED P-5055, Radiation Health Protection Manual. All pocket dosimeters cha!! be models approved in the Coordinated Shipboard Allowance List (COSAL) for RADIAC equipment and shall have current calibration. Pocket dosimeters shall not be used past the calibration due date on the calibration label'. Pocket dosimeter readings shall be recorded on Figure 1, enclosure (3). 2. RADIOGRAPHERS._ All radiographers shall comply with the following requirements: a. When working in the radiographic vault, or in proximity to a radiographic exposure device or source container, each radiographer shall. wear a TLD and two low-range (0-200 mese) pocket dosimeters. The pocket dosimeters and the TLD shall be worn adjacent to one another, at waist level and on or near the front of the body. b. Each radiograpner shall recharge and zero his/her pocket dosimeters at the start of each work day or work shift in which a souece will be used or prior to commencing operations with a source. Absolute zero need not be attained, however, if the pocket dosimeter cannot be brought to read less than 10 mR it must be rejected and returned to a calibration f acility f or evaluati on, c. Each radiographer is responsibir for monitoring his/her own radiation exposure. He/she shall read the pocket dosimeters and record the initial hnd final readings in the Dosimeter Log each working day that a source is used. See Figure 1, enclosure (3). When involved in the handling or use of radiographic sources, the radiographer shall read the pocket dosimeter ' f requently to check radiation exposure. d. If a radiographer deter. mines thdt.he/she has exceed'ed an administra.tive controlulevel or 'has reason to' suspect Ahat he/she has received an excessive exposure, he/she shall report the occurrence via the supervisory chain to the RSO. Following such an occurrence, the radiographer shall not work in a radiation-area until approval by the RSO has been obtained. ~ Enclosure (3) {

j REPDEPTINST 5100.3N I 2 21,%R 1999 e. If a TLD receives an excessive exposure when it is not being worn (such as accidentally dropped or lost in a restricted area), the radiographer shall report this occurrence via the + supervisory chain and shall not return to work until cleared by the R90. f. If one pocket dosimeter goes off-scale, the individual shall immediately be removed _from radiation work and the primary dosimetric device shall be immediately and expeditiously returned , to the NAVMEDCOM Dosimetry Center for evaluation. The individual may be allowed to" return to work before the results of the primary dosimetric evaluation are known if all of the following conditions are mets i (1) The Radiation Safety Officer (RSO) can clearly i establish that the off-scale pocket dosimeter is defective. (See below.) AND (2) The pocket dosimeter which was not off-scale is functioning properly. 20 (3) The RSO has determined that the individual was not p exposed beyond permissible limits in NAVMED P-5055 or established administrative limits. g. In the event one pocket dosimeter goes off-scale, the following checks shall be pwrformed on both dosimeterse l (1) Drift Check. Charge to zero, then observe after,two hours. Within the context of this procedure a defective pocket ~ dosimeter is one that undergoes greater than one-fourth of full scale deflection (upward drift) within two hours. (2) Response Check. The following procedures shall be ,used :- L O (a) Ensure that the pocket dosimeter has a current 6 calibration sticker attached. (NOTE: ' Re-calibrations are , required evyy. six mesnths. ) , / *. (b) Zero the pocket dosimeter to be checked. (c) Tape the pocket dosimeter to a cesium-137 check ' source such as those used for radiography survey meters. Enclosure (3) ? .,n.-

If both pocket dosimeters go off-scale or if only one goes off-scale and the other indicates radiation exposure of greater than 10 mR, the individual shall not be permitted to return to radiation work until the results of the primary dosimetric device evaluation are known. 1.

This restricted area barrier shall be conspicuously posted with signs containing the radiation l symbol'and the words'" Cautions Radiation Area". The barrier shall be-initially established at a calculated dietance where the radiation level, is two.mrom/haur except as authorts:ed below for short duration exposures. When approved by separate written entry and initialed by the RSO in paragraph 2 of Temporary Site Radiographic Operations Authorization (see Figure 1, enclosure (7)), the radiation level at the restricted area perimeter may exceed two wom/ hour f or short duration exposures provided thats a.

1. This attachment describes the permanent radiographic facility. 2. The radiographic f acility is located on the 01 1= vel of the ship between Frames 126 and 127 on the ship's centerline.. All radiographic operations performed in the i f acility are done with the sealed source inside the Radiographic Vault. (See j attached figures) The density of the lead installed is 11.4 g/ce* and thickness varies from 2-3/4 inches to 4 inches exclusive of structural steel plating. The inside dimensions of the vault are 44 x 48 x 96 inches. The vault door is constructed in such a manner that radiation stretning is prevented.. A two-inch tube is provided in one corner of the vault to permit remote operation with the wource drive cable. The comortment immediately below the vault is the Auxiliary Power Shop (E Division). On the starboard side of the vault is the NDT Labratory. On the port side of the vault is a material handling trunk, not nemally occupied. Formed of ths vault is Fanroom 01-121-0-Q, not normally occupied. Aft of the vault is the NDT Laboratory. Above the vault is the 02 level weatherdeck. 3. The vault is equipped with gamma alares which provide a visible signal at the vault door when the sealed source is exposed inside the vault An audible alare is sounded when the vault door is opened with the sealed source exposed. 4. With an uncollinated 100 Curie iridium-192 source located in the vault, near the walls the radiation level is less than two mR/ hour at one foot from the vault surf ace. See the attached survey. Posted CaF TLDs on bulkheads of compartments immediately adjacent to the vault show that no individual-receives greater than 100 mRee dose in z.; + seven days of continuous exposure. Normal operation utilizes a collientor to reduce exposure. L 5. A " Caution - High Radiation Area" sign is posted outside on the vault door and.. l. inside the vault. A " Caution - Radioactive Material" sign is posted outside on the l vault door. l a n; QC f' Enclosure (18) { il-
