PA-1000

Environmental Radiation Monitor "Radi"

Every day, wherever we go, we are exposed to minute amounts of environmental radiation.* This environmental radiation is emitted continuously, day and night, from various objects and substances in the natural world and our living environment.

Most environmental radiation consists of three types: alpha rays (α), beta rays (β) and gamma rays (γ).  HORIBA's PA-1000 "Radi" environmental radiation monitor makes it easy for non-specialists to measure even minute levels of gamma rays.

* Environmental radiation, also known as natural radiation, includes radiation emitted from space, soil, stones, the ground and the air, as well as from manmade objects such as concrete and buildings

 

 

 

Подразделение: Radiation Monitor
Производитель: HORIBA, Ltd.

Features

  • Easy measurement by Anyone, Anytime, Anywhere

  • High performance detection with a CsI (Tl) scintillator
    The Radi can measure radiation levels ranging from normal natural radiation to levels 100 to 200  times that intensity. Even non-specialists will find it easy to measure radiation of 0.001 - 9.999 µSv/h.

  • Splash-resistant construction
    The Radi can be used with confidence even if there are water droplets on the surface.  (JIS water resistance protection grade IPX4)

  • Compact and lightweight (175 g / 6.2 oz)

  • Uses two AA batteries.
    Battery life 50 hours or more (when manganese dry cell batteries are used)

Applications

  • For Improvement of the safety and security for the local residents and local communities nearby the nuclear power plants.
