The Use of FISH Techniques for Retrospective Biological Dosimetry (COD), Final report (summary)

Project ID: FIGD-CT-2000-20040
Funded under: FP5-EAECTP C


An important outstanding problem in radiological protection is to assess the radiation risk at low doses and dose rates. There are very few direct human data to support an estimate. Present estimates rely upon an extrapolation of data from high doses and high dose rates using simple models of unproven validity. One way to obtain more direct evidence is to study epidemiologically populations that have been exposed above normal background levels over a long period of time. Radiation workers and members of the general population who live in areas of high activity are possible groups that could be studied.
One necessary parameter is dose to the individuals involved in such a study. At present techniques involve personal monitoring in the case of radiation workers or dose reconstruction for a population in a contaminated area. The reliability of these measurements is open to question. Personal monitors can be exposed without being worn and a person can be exposed without wearing a monitor. The memory of a person¿s movements over many decades could be suspect. A method of biological dosimetry, which acts as a permanent record of the dose to the individual, could be very useful.
