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. [...]

Determination of Luminosity With Thermal Neutron Counting Using TPX Detectors in the ATLAS Cavern in LHC Proton-Proton Collisions at 13 TeV
/ Sopczak, André (IEAP CTU, Prague) ; Ali, Babar (IEAP CTU, Prague) ; Begera, Jakub (IEAP CTU, Prague) ; Bergmann, Benedikt (IEAP CTU, Prague) ; Billoud, Thomas (Montreal U.) ; Biskup, Bartoloměj (IEAP CTU, Prague) ; Burian, Petr (IEAP CTU, Prague) ; Caforio, Davide (IEAP CTU, Prague) ; Heijne, Erik (IEAP CTU, Prague) ; Janeček, Josef (IEAP CTU, Prague) et al.
A network of Timepix (TPX) devices installed in the ATLAS cavern has the unique capability of measuring the luminosity with thermal neutron counting in Large Hadron Collider proton-proton collisions at 13 TeV. Compared with the hit-counting method, the method of thermal neutron counting has the advantage that it is not affected by induced radioactivity. [...]

Comparison of measurement and simulation of ATLAS cavern radiation background
/ Heijne, E (CERN ; IEAP CTU, Prague) ; Koi, T (SLAC) ; Leroy, C (Montreal U.) ; Oberlack, H (Munich, Max Planck Inst.) ; Pospisil, S (IEAP CTU, Prague) ; Sherwood, P (Imperial Coll., London) ; Shupe, M (Arizona U.) ; Solc, J (IEAP CTU, Prague) ; Suk, M (IEAP CTU, Prague) ; Takai, H (Brookhaven) et al.
Sixteen Medipix2 pixel detector based (MPX) devices were
operated at various positions within the ATLAS detector and cavern
continuously from early 2008 up to 2013. In addition to photons,
each MPX detector is capable to detect charged particles, and
neutrons as it is covered with a mask of converter materials
dividing its area into regions sensitive to thermal or fast
neutrons. [...]
