AbstraktAbstract

An application of the use of MPX detectors for the measurement of induced radioactivity in the Large Hadron Collider (LHC) experiment environment is presented. The sixteen ATLAS-MPX detectors measured the associated photon ambient dose equivalent rate (H*(10) rate) in ATLAS due to the LHC operation. It is presented that in 2010 the average H*(10) rate determined with all MPX detectors varies around 0.015 mu Sv/h in the ATLAS cavern. In 2013, roughly after 50 days from the end of high luminosity physics runs, the highest H*(10) rate measured with the MPX detectors has reached 14.9 mu Sv/h (in inner detector region). All the other dedicated MPX detectors measured H*(10) rate which reached the value up to 1.3 mu Sv/h, depending on the MPX detector.
