Application of dose coefficients



In the last version of the IDEA Expert System the dose coefficients are given for the adult worker and for members of the public as well. For the members of the public the dose coefficients are specified for adults and for younger persons in the age of 15 years, 10 years, 5 years, one year and 3 months, respectively. There is no specification with respect to gender, i.e. the dose coefficients are valid for both males and females. In the OIR dataset, however, there are gender-specific dose coefficients for male and female workers.


So, in the new version IDEA+ the dose coefficients are applied in the following way:

  • For workers the new dose coefficients are applied as far as available, i.e. for the 27 elements covered by ICRP Publications 134 and 137. In this case the software checks the gender of the worker and allocates the dose coefficients accordingly. For the remaining elements the software applies the dose coefficients in the same way as in the last version of IDEA. 
  • For members of the public all dose coefficients are applied in the same way as in the last version of IDEA.
