Dear Congressman Gillmor:

I am responding to your December 3, 1992, letter to Mr. Dennis Rathbun, Director of Congressional Affairs, pertaining' to correspondence from Mr. Ralph L. Harding to the Secretary of the Army. Mr. Harding raised several concerns about the Army Reserve unit based in Bryan, Ohio. One of these concerns rega.ded a " Danger Radioactive Material Stored Inside," sign posted on the outside of the building. The Nuclear Regulatory Commission's regulations regarding posting of facilities containing radioactive material are contained in 10 CFR 20,203, entitled, " Caution Signs, Labels, Signals and Controls" (see ). By reviewing our files and contacting the Department of the Army, the NRC staff determined that the Army Reserve Unit based in Bryan, Ohio, only possesses self-luminous devices such as compasses or watches, and chemical agent detectors. These devices, although containing-small quantities of radioactive material, give off no penetrating radiation, pose no threat to individuals in the vicinity of the building and do not require the Army Reserve Unit to post the outside of their facility to comply with NRC regulations. Army-personnel have informed NRC staff that currently the radioactive material sign has been removed from outside of the building. Similar self-luminous watches and compasses ara available to the general' public. The chemical agent detector functions similarly to a commercial smoke detector. Enclosed for your information are 160028 h, ff h 9302170155 930113 PDR PR 20 MISC PDR k .a

a The Honorable Paul E. Gillmor - 2 device registration sheets for a typical self-luminous compass (see Enclosure 2) and a chemical agent detector (see ). I trust that this reply will respond to your constituent's concerns. Sincerely, / 'EfC \\v / da es M. T lor 7 ecutive Director V tor Operations

When folded, the compass measures approximately 3 inches (7.62 cm) x3 inches (7.62 cm) x2 inches (5.08 cm). The case is made of a die-cast aluminum case bottom, rubber-seal cup, damping shell, dial, dial cover, and bezel assembly. The dial is inserted into a hole in the damping shell so that it can turn freely, then the dial cover is placed on top of the damping shell. The seal cup is then placed over the entire assembly. The case bottom is then attached. A rubber seal cup is compressed between the damping shell and case bottom as four screws that hold the-shell and case bottom together are tightened. Seven Hydrogen-3 (tritium) vials, with a total activity of 120. millicuries (4.44 GBq) are used as light sources.for viewing the compass under dark conditions. The vials used are manufactured by mb/Microtec of Bern, Switzerland (models 400/1, 400/3, and 400/6). All these vials are held in place with silicone adhesive.

(2) the air pump assembly and (3) the detector cell assembly which contains the Americium source. These three components are secured in a high impact plastic case. The use of these components allows rapid non-technical repair of a unit in the field. ~5e device also has an optional battery pack that can be secured to the bottom of the device or it can be powered by a 24-volt supply line. The device can be a portable unit or a mounted at a fixed location, depending on the situation. The unit. has been constructing using materials that provide for its use in a wide range of environs. LABELING: The sou housing is labeled with the trefoil symbol isotope, activity, date of assa; ,he words, " Caution-Radioactive Material " and the words, " Radiation Exposure an Occur When Cell Module Is Opened. Cell Hodule Should Not Be Dis-Assembled." Additionally, the outside of the case is labeled with the isotope, activity, trefoil symbol, the wcrds, " Caution-Radioactive Material," the words, " Control Disposal Required," and the words, "If Found, Return To Nearest Hili tary Activi ty. " DIAGRAM: i l See attachment. l CONDITIONS OF NORMAL USE: i The device will be used in ambient environmental conditions throughout.the world as an automatic chemical agent alarm. l PROTOTYPE TESTING: l The foil source design used in the device w - been deemed acceptable for. licensing purposes by the NRC. See registration sheet No. NR-136-5-174-U for additional i n fo rma ti on.' Additionally, the Radiochemical Center in England (Amersham) subjected the foil source to the following tests; o Specified form per requirements of IAEA transportation. o Isotope testing in accordance with 1968 requirements. o Exposure to sulphur dioxide, ammonia, hydrogen sulfide, hydrochloric acid, salt spray, and ozone. ...m.,,. ~. _, - y ,.mi..,,__,.,

REGISTRY Of RADI0ACT1yE SEALED SOUCCES AND DEY1CES ,4 SAFETY EVALVATION OF DEV]CE NO: NR-155-D-118-5 D_ ATE _: JUN 151983 PAGE 3 E 4 DEVICE TYPE: Chemical Agent Detector PROTOTYPE TESTING (Cont'd): o immersion in simulated body fluid. o Abrasion tests o Elevated temperature tests up to 1200'C. o Vibration tests o Exposure to cleaning fluids, ethel, acetore trichlorcethf ene. The manufacturer reported no leakage above.005 microcuries for any of the foil sources tested. The entire device was subjected to environmental testing as required by Military Standard 810C. The device was subjected to tests that simulated the worst conditions that may arise during field use. Devices were smear tested after each test. No leakage in access of.f ^5 microcuries was reported. EXTERNAL RADI ATION LEVELE: The Department of the Army reports that: o The maximum radiation dose from the detector is 0.6 mr/hr at the surface, .04 mr/hr at six inches and 0.005 mr/br at 36 inches, o The maximum radiation dose rate from the cell module (source housing) are 1.4 mr/hr at the surface. 0.7 mr/hr at six inches and 0.06 mr/hr at 36 inches. These readings were taken directly in front of the foi'. face. In other directions the levels are insignificant. QUALITY ASSURANCE AND COMTROL: The devices are to be manufactured by a company under contract to the U.S. Department of the Army. The contract clearly specifies what is to be the acceptable specificatic of the device. Also, devices are periodically tested by the Army to ensure that they meet these specifications. Any device that does not meet the specifications is deemed not acceptable for use ur.til the problem can be corrected by the manufacturt LIMITATIONS AND/OR OTHER CONSIDERATIONS OF USE: The device shal1 be distribut'ed by the Department of the Army Hq, U.S. Army ~ o Armament Material Readiness Command, Rock Island, IL., for use by the Department of Defense anywhere deemed acceptable by the licensee. Handling, storage, use, transfer, and disposal shall be determined by the o licensing authori ty.

In view of the extended leak test interval, the applicant should develop an o accountability control program to keep track of all devices in storage and use. tbk!$nN! aN1)!NioNhafehMyg g ggpa gp e uns as descr%e SAFETY ANALYSIS SUg,ARY: The Model M43Al chemical agent detector has been designed to give fast, accurate readings of the concentration of specific gases and to warn of concentration that may be hazardous to the persons deployed in that area. Based on our review of the information and test data cited below, and that the device will be used by persons trained in its use, we conclude that the chemical agent detector design is acceptable for licensing purposes. 'Furthermore, we conclude that the devices would be expected to maintain their containment integrity of the source for the uses specified in this certificate.
