BR330

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.

• More than 50 years of experience in dosemetry
• Precise and reliable dose determination
• Accredited measurement laboratory in Switzerland and in several European countries

• Germany’s/Europe’s oldest and largest individual dosimetry laboratory
• Individual-, local- and environmental dosimetry at a high level
• Accredited measurement laboratory with over 1.8 million evaluated dosemeters per year

• Manufacturer of high-quality medical devices and
  personal protective equipment
• Leader in quality and innovation in the field of X-ray protection since 1921
• Innovative research and development with experience and craftsmanship

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.
