66 -- LAB EQUIPMENT SOL E27815 DUE 061997 POC Trudy Dartouzos, Contract Specialist, ph: 301/443-2597, fax: 301/443-3651 The Food and Drug Administration (FDA) intends to award a purchase order for 15 X-ray monitors equivalent to the RADCAL Corporation Model 1015FBH with ionization chambers 10X5-6L and 10X5-180. The monitors must be able to measure exposure, exposure rate, exposure integrated over a single pulse of radiation of 1 ms or greater, and the duration of the pulse. The monitors shall be equipped with one ionization chamber which shall be compatible with the Center for Devices and Radiological Health test stand and shall have an active volume not greater than 8 cc. This chamber shall have a measurement range of 1 mR/min to 650 mR/min and energy dependence less than 7% from M30 (HVL = .36 mm AL HC = 14) to H150 (HVL -- 17.0 HC = 100). A second chamber shall have a cross sectional area of 100 mc squared and a range of 1 mR/hr to 650 mR/hr. This chamber shall have less than 10% energy dependence from M50 (HVL = 1.02 mm AL HC = 66) to H150. The calibration accuracy for both chambers shall be +/-5% or better. The monitors and chambers shall be contained within a case no larger than 8" by 10" by 12" and not to exceed 15 pounds. The monitors shall have a digital display and shall be powered by alkaline "D" cell batteries. The batteries shall have a lifetime for 750 hours of operations.
