3. DESCRIPTION OF PROGRAM OR FUNCTION - GARDEC estimates the reduction of dose rates by garden decontamination. It provides the effect of different decontamination methods, the depth of soil to be considered, dose-rate before and after decontamination and the reduction factor.


4. METHODS - This code takes into account three methods of decontamination :
(i)digging a garden in a special way, (ii) a removal of the upper layer of soil, and (iii) covering with a shielding layer of soil. The dose-rate conversion factor is defined as the external dose-rate, in the air, at a given height above the ground from a unit concentration of a specific radionuclide in each soil layer.
