Program-name Package-ID Status AIRGAMMA NEA-1130/01 Tested

Machines used: Package-ID Orig.Computer Test Computer NEA-1130/01 FACOM M-380 IBM 3083

3. DESCRIPTION OF PROGRAM OR FUNCTION - AIRGAMMA calculates quickly the external exposure to gamma rays from a radioactive cloud.

4. METHOD OF SOLUTION - The external exposure is calculated by interpolating the normalized doses providing on the basis of the Gaussian plume model.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM - Memory requirement is 30 Kbytes.

6. TYPICAL RUNNING TIME - About 1.6 seconds are required to calculate the sample case on FACOM-M380.

NEA-1130/01:

NEA-DB ran the test cases included in this package on an IBM 3083 computer. The following CPU times (in seconds) were required: 1.3 (case 1); 26.6 (case 2); 169.5 (case 3).
