In the final report of work package 2 a further investigation of the collective of interven-<br />
tional cardiologists and radiologists and of flight crew members was therefore recom-<br />
mended. The results of work package 2 were discussed in detail with BfS. As a result the<br />
BfS commissioned the further piloting of both collectives.<br />
6.3 Results of work package 3<br />
An epidemiological study is feasible in principle in both investigated collectives.<br />
- Taking into account the expected participation rates, both collectives are large enough<br />
to detect a difference in prevalence of 23 % to 10 % (as seen in the first few studies on<br />
interventionally acting doctors (Ciraj-Bjelac et al. 2010b)) with a statistical power of<br />
80%.<br />
- For both collectives, a non-exposed comparison collective can be recruited among their<br />
colleagues.<br />
- The collectives are homogenous concerning many factors so that even internal compari-<br />
sons have a high validity.<br />
- For both collectives the registration of risk factors and potential confo<strong>und</strong>ers can be<br />
carried out in the same way and in a fashion comparable to former studies by using<br />
questionnaires.<br />
- Radiation exposure of the lens during work can be reconstructed, even historically, in<br />
both cases. The registration of necessary data can be donepreparative. For the estimation<br />
of radiation doses it is useful to include the results of current research of the EU-<br />
fo<strong>und</strong>ed project ORAMED (Carinou et al. 2011; Domienik et al. 2011; Gualdrini et al.<br />
2011) and of ICRP (update of Volume 74 (Petoussi-Henß 2011)). For interventional<br />
cardiologists and radiologists, a validation of dose estimation using measurementswith<br />
thermoluminescence dosemeters in cooperation with the ORAMED research group is<br />
highly desirable.<br />
- Lens opacities can be objectively documented in a standardised way and classified with<br />
reliable procedures. A comparability with some international studies (among others<br />
those of atom bomb survivors (Jacob et al. 2010b; Mrena et al. 2011; Neriishi et al.<br />
2007)) is therefore feasible.<br />
