IDAC Dose logotype


IDAC-Dose has since 1987 been used by the ICRP to estimate effective dose and absorbed doses to patients from radiopharmaceuticals. It is a free and user friendly computer software, which is easy to install and to calculate doses.
Compatibility: IDAC-Dose2.1 runs on Mac, Windows 7 and 10

About IDAC

IDAC-Dose1.0 (Internal Dose Assessment by Computer) was created by Prof. Lennart Johansson at Umeå University in 1987 and is the sanctioned software by the International Commission of Radiation Protection (ICRP) to estimate the radiation risk for diagnosic examinations in nuclear medicine at hospitals. The software has been used to perform dose calculations from different radiopharmaceuticals in ICRP Publication 53, 62, 80, 106 and 128.
A new version, IDAC-Dose2.1, was developed based on the ICRP specific absorbed fractions and computational framework of internal dose assessment given for reference adults in ICRP Publication 133. The software uses the radionuclide decay database of ICRP Publication 107 and considers 83 different source regions irradiating 47 target tissues, defining the effective dose as presented in ICRP Publications 60 and 103.
IDAC takes cumulated activities (total number of disintegrations) per administrerad activity in hours and calculates the absorbed dose and the effective dose. IDAC-Dose2.1 has the possibility to calculate absorbed dose from 1252 different radionuclides of 97 elements.The computer software bases the dose estimations on the latest ICRP SAF values and implements the computational framework for internal dose assessment already used by ICRP. The software is suitable for patients in nuclear medicine.
