RSIC DATA LIBRARY DLC-144




1. NAME AND TITLE OF DATA LIBRARY

DOSDAT-DOE: Dose-Rate Conversion Factors for External Exposure to Photons and Electrons.

2. NAME AND TITLE OF DATA RETRIEVAL PROGRAMS

DOSDAT-R: Retrieval Code to List Dose-Rate Factor Data.

3. CONTRIBUTOR

Oak Ridge National Laboratory, Oak Ridge, Tennessee.

4. HISTORICAL BACKGROUND AND INFORMATION

The data library contains a tabulation of dose-rate conversion factors for external exposure to photons and electrons emitted by radionuclides dispersed in the environment. A dose-rate factor can be regarded as a dose-equivalent rate per unit radionuclide concentration. For a given radionuclide, the dose-rate factors are constants which are determined by the radiation type (photons or electrons) and the energies and intensities of the emitted radiations of that type, the mode of exposure, and the organ of the exposed individual or population for which the dose-equivalent rate is desired.

This is the third widely-distributed compilation computed by the code DOSFACTER. The present data differ from DLC-79/DOSDAT II as follows: no body surface factors are calculated, "total body" factors are replaced by "effective" (weighted) factors, electron dose factors for the skin are calculated at several depths, and output format differs. Non-SI units are used.

5. APPLICATION OF THE DATA

The data are used to estimate the gamma-ray and electron dose rates for various body organs (23) and for an "effective" dose rate for air and water immersion and from ground-surface sources. The data are given for approximately 500 radioactive nuclides.

6. SOURCE AND SCOPE OF DATA

The data were computed by the CCC-536/DOSFACTER-DOE code from the DLC-80/DRALIST library of radioactive decay data for approximately 500 nuclides. They are used to estimate the gamma-ray and electron dose rates for 23 body organs and the "effective" dose rate for air and water immersion and from ground-surface sources.

7. DISCUSSION OF THE DATA RETRIEVAL PROGRAM

The retrieval program simply lists the data. No other input is required. The PC version was compiled with the Ryan-McFarland compiler version 2.42 and linked with PLINK86.

8. DATA FORMAT AND COMPUTER

EBCDIC card images; Data General MV/family and IBM 3033 (A) and IBM PC (B).

9. TYPICAL RUNNING TIME

Not applicable.
