Dosimetry Research

Dosimetric research and development going on at the Nuclear Security Department (NSD) embraces the fields of environmental, personal, retrospective, accidental, reactor, and radiation technology dosimetry. We are developing and characterising novel dosimetric materials, as well as new analytical methods. Our most successful techniques is retrospective dosimetry, which has been further developed in the frame of the EU project FP7 (Booster 2010-2013) and closely related to the nuclear forensic analytics as well.

The essence of the method is that the dose absorbed by the persons injured during an unexpected event (accident, terror attack) can be estimated afterwards. For this, certain natural substances (dolomite, sand) or electronic appliances containing also components utilized as basic materials in dosimetry (e.g. aluminium-oxide) are excellently suitable. Such appliances can be e.g. small resistors dismounted from cell phones. Those goods store irradiated dose, which can be developed by optical or thermoluminescent methods and can be estimated. In this way, knowledge can be gained on the dose degree what a given person suffered from. Having this information, further medical treatment can be planned.
