Benchmark studies of induced radioactivity produced in LHC materials, Part I: Specific activities

Radiat Prot Dosimetry. 2005;116(1-4 Pt 2):6-11. doi: 10.1093/rpd/nci051.

Abstract

Samples of materials which will be used in the LHC machine for shielding and construction components were irradiated in the stray radiation field of the CERN-EU high-energy reference field facility. After irradiation, the specific activities induced in the various samples were analysed with a high-precision gamma spectrometer at various cooling times, allowing identification of isotopes with a wide range of half-lives. Furthermore, the irradiation experiment was simulated in detail with the FLUKA Monte Carlo code. A comparison of measured and calculated specific activities shows good agreement, supporting the use of FLUKA for estimating the level of induced activity in the LHC.
