3. DESCRIPTION OF PROGRAM OR FUNCTION

The code predicts the results and main characteristics (detection limits, determination limits, measurement limits and relative precision of the analysis) of neutron activation analysis (instrumental and radiochemical). Gamma-ray dose rates for different points of time after sample irradiation and input count rate of the spectrometry system are also predicted. The code uses standard Windows user interface and extensive graphical tools for the visualization of the spectrometer characteristics (efficiency, response and background) and simulated spectrum. Optimization part is not included in the current version of the code.
IAEA1411/03
This version corrects some minor bugs of version 02.

4. METHODS

The code simulates gamma-ray spectrum of activation products for the specified analysis conditions. These are analysis time mode, analyzed sample mass and elemental composition, characteristics of irradiating neutron flux and irradiation conditions, gamma-spectrometry measurement geometry and background conditions, as well as detector and spectrometry system parameters. During calculation of gamma-ray yields of activation products the burnup and buildup of both radioactive and stable isotopes are taken into account.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Neutron self-shielding and gamma-ray self-absorption effects are neglected. Epithermal activation is calculated using infinite dilution resonance integrals with minimum energy 0.1 eV and 0.55 eV for irradiation without and with Cd shielding respectively. It is assumed that radiochemical separation is carried out just after the sample irradiation and it takes negligible time. The detector response is simulated assuming point source at the detector axis, neglecting by pile-up and true-coincidence summing effects, using zero-dead-time approximation and simplified backscatter-peak model.

6. TYPICAL RUNING TIME

The execution time varies from less than 1 second (single element sample) to approximately 60 seconds (multi-element sample) when CPU Pentium 1 GHz is used.

7. UNUSUAL FEATURES

The code can be used for research as well as for educational purposes.

8. RELATED OR AUXILIARY PROGRAMS

MCNP code was used for generating detector responses. PREPRO-2000 and FCONV programs were used at the preparation of the program nuclear databases. A special program was developed for viewing, editing and updating of the program databases (not included into the present program package).
