Project objectives



  1. Development of a new radiological dosimetry system which comprises low Zeff and high Zeff luminophores in Tandem combinations and portable and mobile OSL reader.
  2. Investigating BeO, MgO, TiO2, ZnO-based luminophores with low Zeff and YAM, YAP, YAG–based luminophores with high Zeff have a high potential in radiological emergency dosimetry. To show their dosimetric characteristics comply with requirements for emergency dosimetry.
  3. Modification of stimulation conditions in the portable and mobile OSL reader would allow measurements from high Zeff luminophores as well as low Zeff luminophores.
  4. Applying mathematical methods and models to the studied emergency radiation dosimetry system using Monte Carlo methods to simulate the transport of photons.  

Expected outcomes:

  1. New Tandem dosimeter systems employing two different dosimeter combinations for effective energy and absorbed dose measurements in a mixed radiation field in a radiological emergency.  
  2. A portable and mobile OSL reader designed to obtain the individual’s dose and effective energy of the unknown radiation beams required for use in emergency circumstances.
  3. Providing body dose and effective energy of mixed field in a few minutes. During the radiological emergency, governmental response mechanisms such as sheltering or evacuation are initiated based on fast-defined projections of public radiation exposure-dose and radiation type. End products from this project are expected to become a part of the emergency planning of civilian and governmental organizations. The outcomes of the project may help better management of medical treatment in mass casualty exposure scenarios.
  4. Special radiation information on isotope identification. Radiation emergencies often involve a complex combination of different types of radiation exposure: exposure to high-energy radiation, external contamination (clothes, skin) with radio-isotopes, and internal contamination (i.e. internal organs – lungs, bowel, etc) with radio-isotopes. Whereas the approach to external contamination is the generic cleansing independent of isotope identity, the medical treatment of internal contamination involving the use of antidotes is critically dependent upon which isotope is involved. For instance, uranium exposure requires the use of large quantities of sodium bicarbonate to alkalize the urine and prevent kidney injury, whereas cesium exposure is treated with ferric ferrocyanide (Prussian blue) to reduce gastrointestinal absorption (see PMID:25004166).

  5. Increased concern for emergency dosimetry to the civil and military branches of government and many industrial enterprises increased visits and interaction between them.
  6. Dissemination of knowledge surrounding the dosimetry system among authorities, scientific institutions, and end-users, aiming at the widespread adoption of new methods and products.
