The RaySafe 452 (the instrument) is used with different lids, or without
lid, to quantify dose, dose rate, mean photon energy, counts and
count rate.
The instrument consists of two automatically handled sensor systems:
1. A Geiger-Müller pancake, used at low dose rates and, without lid,
as an α / β / γ (alpha, beta, gamma) counter.
2. A cluster of solid-state sensors, used at medium to high dose
rates.

NOTE The entrance window of the Geiger-Müller pancake (G in

be touched. The Geiger-Müller pancake is also sensitive to
mechanical shock.
