1. NAME AND TITLE

ACRO: Calculation of Organ Dose from Acute or Chronic Inhalation and Ingestion of Radionuclides.

2. CONTRIBUTOR

Tokai Works, Power Reactor and Nuclear Fuel Development Corporation, Tokai, Ibaraki, Japan.

3. CODING LANGUAGE AND COMPUTER

Fortran IV; IBM 360/370.

4. NATURE OF PROBLEM SOLVED

ACRO estimates the burden and dose to the organs or tissues as a result of inhalation or ingestion of radioactive materials.

5. METHOD OF SOLUTION

A composite organ of the tracheo-bronchial, the pulmonary parenchyma and the pulmonary lymphatic system is used for the estimation of doses due to inhalation and the International Commission on Radiological Protection (ICRP) Pub. 2 model has been adopted for the estimation of ingestion. A simple four-compartment model for the gastro-intestinal tract is applied to compute exposure to the tract.

6. RESTRICTIONS OR LIMITATIONS

maximum number of library records: 3000

maximum number of nuclides (input): 30

maximum number of organ codes (input): 30

7. TYPICAL RUNNING TIME

It requires about 10 minutes to calculate the sample input data on the IBM 370/@115II.

8. COMPUTER HARDWARE REQUIREMENTS

The code is operable on the IBM 360/370 computers. It requires 260 K bytes of memory and a disk for 3 work files, each file requiring about 170 tracks.

9. COMPUTER SOFTWARE REQUIREMENTS

A Fortran H compiler is required. The program executes under an IBM DOS/POWER/VS or IBM OS/MVS operating system.
