66 -- X-RAY SURVEY METER SOL A229946 DUE 070299 POC Patricia Wright, Contracting Officer (301) 827-7163 The Food and Drug Administration has a requirement to purchase an X-Ray Survey Meter with the following performance specification: 1) Dynamic Range: 0.01 mGy to 1 mGy air kerma rate (1 mR/hr to 100 mR/hr minimum range; for rates above this range and up to at least 10 mGy/hr (1 R/hr) the meter shall read full scale until removed from the radiation field. 2) Energy Response: + 30% between 40 keV and 150 keV effective energy, and + 50% between 30 KeV and 1 MeV effective energy. 3) Display: linear, analog display; no more than one decade per range selection; although the scale shall have numerical markings, the units shall not be indicated (i.e. "mR/hr", "uGy/hr", "CPM", "mrem/hr", "uSv/hr", etc. shall not appear anywhere on the instrument). 4) Linearity: the meter shall be linear with exposure rate within + 15% on all ranges. 5) Response Time: not exceed 5 seconds on the most sensitive scale and not to exceed 2 seconds at 0.5 mGy/hr (50 mR/hr) and above. 6) Calibration Accuracy: for an x-ray beam of 100 keV effective energy, the arbitrary display units shall correspond to the exposure rate in mR/hr within + 20%. 7) Power: the meter shall be powered by standard alkaline batteries, size AA, D, 9V transistor type; the battery life shall exceed 200 hrs of operation. 8) Battery Check: the battery status shall be indicated on the display. 9) Size and Construction: the survey meter shall be made of high-impact material, shall not exceed 3.5" x 8" x 2", and shall weigh no more than 18 ounces. 10) Entrance Window: the sensitive area of the detector (where the instrument is to be exposed) shall be clearly and permanently marked on the outside of the case. 11) Information to be provided: one instruction manual shall be provided with each instrument; at least one (total) set of schematic diagrams and a complete component list shall be made available. 12) Information to be provided with bid: a complete set of specification and the GM tube's energy response curve must be submitted in order to be considered. This requirement is issued as a Request for Quotation. Sources may submit descriptive literature which fully demonstrate that their product meets the performance specification which shall be considered by the agency. Quotes submitted in response to this requirement shall be submitted by July 2, 1999, 3:00 p.m. Eastern Time. The requirement is will be awarded as a simplified acquisition in accordance with FAR Subpart 13.5. Posted 06/16/99 (W-SN343911). (0167)
