3. DESCRIPTION OF PROGRAM OR FUNCTION

PIEDEC calculates from measured data by a whole body counter or bio-assay test, the initial inhaled or ingested activity and effective dosd e equivalent. The program features the use of specific effective energies and the compartment transfer model based on ICRP Publication 30.

[ top ]

4. METHOD OF SOLUTION

The transformations of radioactive nuclides in each source organ are calculated by the integration of an analytically solved retention function. This integration is numerically performed by the Gauss Legendre method. The effective dose equivalent is obtained from the multiplication of specific effective energies and the transformations.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

The application of this code is rectricted to the following 14 nuclides: 58Co, 60Co, 59Fe, 54Mn, 134Cs, 137Cs, 131I, 133I, 238U, 239Pu, 240Pu, 241Pu, 241Am, and 3H.

6. TYPICAL RUNNING TIME

The PIEDEC code runs in approximately 5 seconds on the FACOM-M380 computer for one case.

NEA-1084/01

NEA-DB ran the test case included in this package on an IBM 3083 computer in 126 seconds of CPU time.

7. UNUSUAL FEATURES OF THE PROGRAM

The application of analytically solved retention functions saves running time and improves the accuracy.
