More isotopes
The last Version of the IDEA Expert System (Version MV-03.6.7) includes 63 elements with 112 isotopes, the biokinetic functions and dose coefficients of which being based on the ICRP Publication 30 series and Publications 54, 68, and 78.
In the new version IDEAplus the biokinetic functions and dose coefficients of 39 out of these elements have been replaced according to the new ICRP Publications 134, 137 and 141 of the OIR series. In addition, 13 elements have been implemented which were not included in the last version of IDEA, i.e. Praseodynium (Pr), Neodymium (Nd), Gadolinium (Gd), Terbium (Tb), Dysprosium (Dy), Holmium (Ho), Erbium (Er), Thulium (Tm), Protactium (Pa), Berkelium (Bk), Californium (Cf), Einsteinium (Es) and Fermium (Fm). So, now 76 elements are included in the expert system with in total 601 radionuclides.
For the update the OIR Data Viewer (Version 4.01.04.19) has been used with special authorization of the ICRP. The OIR Data Viewer provides data for the Reference Worker including values of dose per intake coefficients, dose per content functions, and reference bioassay functions for intake by inhalation, ingestion and for direct uptake to the blood.
Contrary to the previous datasets, the OIR Data Viewer provides biokinetic functions and dose coefficients also for short-lived isotopes with physical half-life values down to 10 min. So, for some elements up to 20 radioactive isotopes are included in the new version of the expert system (see for example Iodine)
