ABOUT RAYSAFE 452
The RaySafe 452 is a hand-held device designed for monitoring
and measuring radiation levels indoors and temporarily outdoors, in
nuclear, industrial and medical applications.
WARNING
The RaySafe 452 does not replace any radiation
protection equipment.
WARNING
The RaySafe 452 is not a replacement for personal
or legal dosimeters.
WARNING
The RaySafe 452 is not approved for use in
environments with explosive atmosphere.
WARNING
Use RaySafe 452 only as specified or the protection
provided in the design may be compromised.
WARNING
Take special care when measuring on intermittent
radiation sources, such as pulsed X-rays or linear
particle accelerators (linacs). See "Intermittent
radiation sources" on page 10.
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
Figure 1 on page 4), is very fragile and should never
be touched. The Geiger-Müller pancake is also sensitive to
mechanical shock.
