| Abstract: | The International Committee on Radiological Protection (ICRP) Committee II Report of 1958 listed recommended Maximum Permissible Concentration (MPC) values for 240 radionuclides. Because of an increase in radioisotope research and uses since 1958 and because of the existence of approximately 1000 radionuclides, additional MPC values were needed. Furthermore, as research yielded newer physical and biological constants, a coherent calculational technique for efficient MPC evaluation became imperative. Based on the existing need for additional MPC values and the availability of new data on which to found MPC value calculation, a three-part computer calculational technique was developed. The computer program consists of a computer logic section written in FORTRAN language, a nine array physical data section, and a multivalued, mutually exclusive biological data section. Using the Texas ASM Data Processing Center IBM 360/65 Computer, approximately 900 radionuclide MPC values were calculated. Agreement between the previously published ICRP Committee II MPC values and the new MPC values was generally close. |
