Abstract : A battery-operated portable combination ratemeter-dosimeter was developed which will measure gamma radiation rate from 0-1000 r/hr in three linear decade ranges. Simultaneously, the integrated dose may be read from a digital display whose range is 0-999.9 r. The least count on the digital register is 0.1 r. The rate may be read with an accuracy of less than !10 percent between -40 and +50 C. The integrated dose from Co60 isotope may be read to 0.1 r or !10 percent, whichever is greater, from -40 to +50 C. Battery life, using two C size nickel-cadmium rechargeable cells is in excess of 40 hr per charge. Package weight, including battery, is less than 3 lb, and size is 4 by 4 by 7 in. (Author)
