"The linear no threshold model is one method to assess the cancer risk from ionising radiation. Although it is currently the most widely accepted model for the purposes of legislation and radiation protection, and is used by the International Commission on Radiological Protection (ICRP) for radiation safety 1, it is the subject of ongoing debates 3-6."
"The model draws from epidemiological data obtained primarily following higher-dose single exposure events such as the atomic bomb explosions over Nagaski and Hiroshima during World War II and extrapolates from outside its range 2. One issue is that this model uses assumptions that are currently not supported by data 3-6."
"Whilst this model is the currently accepted method for determining stochastic effects in radiation protection, some authors argue that other models would be more accurate at assessing risk 4-6."
