Internal dosimetry support system: Multipurpose research computer code

Internal dosimetry support system (IDSS) implements a full set of the ICRP internal dosimetry models, including the new respiratory tract model: it is a 32-bit program that operates under Windows 95. It enables the calculation of the time course of activity, the dose rate, the dynamics of dose accumulation and the committed dose in any tissue of the body; the daily urinary and faecal excretion rates also are available. The results may be accessed for the analysis and interpretation in graphical or numerical form and may be stored for future retrieval. Additional capabilities provide the means for stochastic simulation. IDSS allows analysis of the standard and non-standard exposure conditions and assists in assessment of the dose reliability. The main distinguishing features of IDSS are: processing of an arbitrary time course of the intake function, extended possibilities of data analysis, an orientation to a wide spectrum of research problems, an object-oriented logical structure and a modularity of the code. IDSS assists in the assessment of doses under normal or accidental conditions, both for prospective and retrospective dosimetry problems.
