58 -- DECTECTION OF CONCENTRATIONS OF RADIOACTIVE MATERIAL DUE 022598 POC Renee M. Brown, Contract Specialist, (301) 743-6635 and Keith Plumadore, Technical Representative, (301) 743-6852 X226 E-MAIL: click here to submit paper to Contract Specialist, reneebrown@mail.ih.navy.mil. GOVERNMENT REQUEST FOR INFORMATION -- THIS IS NOT A REQUEST FOR PROPOSALS. The Naval Explosive Ordnance Disposal Technology Division, (NAVEODTECHDIV), Indian Head, Maryland, has a need to detect concentrations of radioactive material which may be present underwater. The radioactive material to be located includes all sources of gamma ray or neutron emission with neutron sources being of greatest interest. The radioactive material can be assumed to be packaged in a metallic or plastic container ranging in volume from 1 to 8 ft. 3, and located in waters up to 100 ft deep. The actual mass of radioactive material in the container cannot be specifically defined, however, the exposure rate constant for gamma ray sources can be assumed to be greater than or equal to 100mR/hr at the container surface. The container is anticipated to be either lost or surreptitiously placed and as such the detection technology would be required to search large areas as efficiently as possible. An example of one potential application would be searching for a 55 gal. drum of radioactive waste which was reported to be illegally dumped in a lake, harbor, or river. The detection technology can be mult-modal (i.e., use of detection technology to find containers/voids/metals in addition to the detection of radiation), however, the successful detection of radiation in situ is paramount and is to be the primary detection technology focus. Solutions which require the movement of a suspected target in order to determine the presence or absence of radiation are not acceptable. It is necessary for the detection technology to be conceived and designed such that it could be successfully deployed and used by semi-skilled personnel operating on small vessels. It is requested that the information submitted be of 3-5 pages in length and address one or both of the following: (1) Wide area detection of an underwater radiation source. Detection method should reduce the bounded search area for further investigation. (2) A sensor capable of localizing the underwater radiation source to within a few tens of meters. Papers can be (1) mailed to: Indian Head Division, Naval Surface Warfare Center, Supply Department, Bldg. 1558, Attn: Ms. Renee M. Brown, Code 1143E, 101 Strauss Avenue, Indian Head, Md 20640-5035; or (2) email to reneebrown@mail.ih.navy.mil. Deadline for submission is 25 February 1997. Once the concepts have been received and reviewed, the Government will consider issuing a Broad Agency Announcement to solicite proposals in FY 1999. For technical questions contact Mr. Keith Plumadore at (301) 743-6852 X226. (0023)
