INTRODUCTION TO RADIOLOGICAL DEFENSE PLANNING

Abstract

Planning of RADEF countermeasures is based on the availability of basic radiological data and on techniques for applying such data. The data and their parameters are (1) a decay curve representing decrease of radiation intensity (r/hr) with time after a detonation; (2) standard intensity, i.e. radiation intensity corrected to one hour after detonation; and (3) time of arrival after fallout. Major parameters involved in the planning techniques are (1) the shelter shielding residual number RNI, where the residual number is the ratio of the exposure dose (or dose rate) received at a given location when a countermeasure is applied to that received without the countermeasure; (2) the shelter stay (or exit) time; (3) the postattack operational residual number RN2 for decontamination crews, evacuation, or other early postattack countermeasures; and (4) the long-term postattack residual number RN3. The use of such factors in the solution of RADEF problems is described, and data for making planning calculations for a number of RADEF situations are presented in the form of graphs.
