Now I am going to describe how Busby differentiates the recently developed European model (ECRR) on evaluating radiation risk from the ICRP model. The following is excerpted from this link
MAJIA HERE: So, what the ECRR model has done is to weight the radiation dose so that it incorporates the biological impact on DNA rather than simply looking at the summative effect of the absorption of the radiation into tissues (at least, that is my understanding)
The ECRR's 2010 Recommendations can be found here
It is interesting to note that in the first link I've provided (http://euradcom.org/publications/iodinedosecalc15042011.pdf) Busby notes that even the ECRR's model fails to adequately predict the impact of radiation on children because they are so much more biologically vulnerable than adults.
Thus, Busby writes:
"The dose coefficient is perhaps as much as 5 times greater for children. Infant leukemia increased after Chernobyl at levels where the ICRP foetal doses from Caesium-137 were about 50microSieverts and the ECRR coefficients for Cs-137 would not have predicted these increases"
