1. NAME AND TITLE OF DATA LIBRARY
UNGER: Effective Dose Equivalent for Specific Radionuclides.
2. NAME AND TITLE OF DATA RETRIEVAL PROGRAMS
None.
3. CONTRIBUTOR
Los Alamos National Laboratory under sponsorship of DOE/DP-MA
4. HISTORICAL BACKGROUND AND INFORMATION
UNGER is a data set of gamma-ray fluence-to-effective dose factors and specific dose constants for nuclides important to dosimetry and radiological assessments. It is an update to ORNL/RSIC-45/R1 (1982) based on DLC-80/DRALIST radioactive decay spectra and ANSI/ANS-6.1.1--1991 fluence-to-dose factors. ORNL/RSIC-45/R1 was based on the fluence-to-dose factors of ANSI/ANS-6.1.1--1977.
5. APPLICATION OF THE DATA
The data are used to assess the radiological hazard of the various radionuclides from the unshielded dose rate at 1 meter (the specific dose constant).
6. SOURCE AND SCOPE OF DATA
The fluence-to-dose factors of ANS-6.1.1 is applied to the gamma-ray intensity for each energy of each nuclide of the Kocher compilation (DLC-80) and summed to give the total anterior-posterior (AP) factors and specific dose constants. Gamma rays of less than 10 keV were neglected. The results are compared to the results of the 1982 publication.
7. DISCUSSION OF THE DATA RETRIEVAL PROGRAMS
There is no retrieval program. However, the program for calculating the dose factors and specific dose constants, implemented on a PC using the Microsoft 5.0 compiler, is included.
8. DATA FORMAT AND COMPUTER
ASCII files; IBM PC
9. TYPICAL RUNNING TIME
The code took less that a minute on a 25-MHz PC 386 to generate the output data.
