DEVELOPMENT OF A NATIONAL EMERGENCY PLAN FOR MEDICAL DIAGNOSTICS AND THERAPY OF DETERMINISTIC EFFECTS AFTER RADIATION ACCIDENTS.

abstract：:In 2012, the International Commission on Radiological Protection issued a recommendation for a reduced annual eye-lens dose limit in the face of mounting evidence of the risk of cataract induction. This led to worldwide research efforts in various areas including the dose simulation in realistic eye-models, the produc...

abstract：:Dose verification in heavy-ion beams using passive dosemeter systems, e.g. thermoluminescence dosemeters (TLDs), is crucial due to the changing efficiency of the dosemeters for different ion species and linear energy transfer (LET) values. This behaviour leads to a falsification of absorbed dose that can be significan...
