Presentation Title: Individual Monitoring from external radiation


Abstract

The challenge of today in individual monitoring is to provide reliable, accurate and, where possible, on-line personal dosimetry for occupationally exposed workers for all limiting quantities (whole body, eye lens, extremities, brain, heart,…), regardless of the protection methods used.
More specifically, quite some work needs to be performed on eye lens dosimetry: formalisms to measure eye lens doses, to develop practical eye lens dosimeters, and to test and compare different eye lens dosimeters. There is also a lack of data for eye lens doses of workers in different fields, where it is also needed to explore correlations of eye lens doses with other dose quantities, to determine reference eye lens doses for different procedures, and to test and improve the efficiency of different protection measures.
Another important task in the field is the extremity dosimetry. Development of practical extremity dosimeters are called for, to test and compare different extremity dosimeters, to explore correlations with other dosimetric quantities, and to improve dosimetry in mixed beta/gamma fields, especially low-energy beta fields. Determination of the best algorithm for double dosimetry and development of the best method to monitor effective doses in case of inhomogeneous irradiation is another high challenged topic.
Finally, neutron dosimetry is still a very challenging task as neutrons are present in mixed-fields, they are indirectly ionizing particles and pose more problems for their detection than other types of radiation. Their energy may cover extremely large energy ranges from 9 (nuclear industry) to 12 (particle accelerators, flight altitudes) orders of magnitude, and their “quality” and subsequently their conversion coefficients from fluence to dose varies by a factor of 50 over the entire energy range.
The talk will present the state of the art in individual monitoring field from external radiation, present the current needs and future trends and challenges.
