LARS: Floor Contamination Monitors

Product description

In order to check large surfaces, for example transfer stations for fuel element containers for radioactive contaminations, we offer several technical solutions.

For example, the LARS system (Large Area Radiation Scanner) can be used to measure large indoor and outdoor areas. The integrated detector can be moved from 5 to 35 mm distance to the floor surface, depending on its structure.

In cooperation with the Spanish company NUSIM, we have equipped almost all Spanish nuclear power plants with LARS systems. Between 2008 and 2009 we have supplied 12 units.
