Radiation protection and eye lensdosemetry redefined. The BR330 protects the user’s eyes from scattered radiation from all angles of incidence and at the same time offers the possibility to combine dosimetry and X-Ray protective glasses.
The common goal of setting new standards for radiation protection glasses and eye lens dosemetry has united the three project partners Dosilab, the AWST Evaluation Centre of the Helmholtz Centre (with April 1, 2020 transition into Mirion Technologies GmbH ) and MAVIG.
European EURATOM Directive
For the first time the European EURATOM Directive 2013/59 limits the annual value for the eye lens dose at a mandatory threshold of max. 20 mSv per year. However, even below this limit the exposure to radiation is to be kept as low as possibly achievable. In addition, regular monitoring of the eye lens dose is mandatory for the risk group of occupationally exposed persons – in accordance with the new Radiation Protection Ordinance (31.12.2018), and applicable with a potential organ dose equivalent of 15 mSv.
Integration of Dosemeters
In the case of monitoring the eye lens dose, a constant position of the dosemeter(s) is most ideal. Together with project partners AWST Evaluation Centre of the Helmholtz Centre and Dosilab, MAVIG has developed a new type of radiation protection glasses that integrates lens dosemetry into the approach in a beneficial way. The BR330 glasses allow the use of dosemeters due to the patented dosemeter connection on the left, right or on both sides. The dosemeter connection has been designed in such a way that there are no user restrictions and yet the best possible dosemetry is guaranteed.
