DESIGNED with plant-based plastic material Helping to reduce petroleum consumption EASY MEASUREMENT — by Anyone, Anytime, Anywhere Environmental Radiation Monitor PA-1000 MEASURING the presence of environmental radiation around us The HORIBA Radi: Able to measure the environmental radiation (gamma rays) in our daily lives starting from 0.001 µSv/h 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 handy 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

High performance detection radiation levels ranging from normal natural radiation to levels 100 to 200 times that intensity. Even non-specialists will find it easy to accurately measure radiation of 0.001 - 9.999 uSv/h. • Alpha rays (a): Alpha rays are streams of positively charged particles made up of two neutrons and two protons (helium nucleus). In the natural world, alpha rays are given off by radium 226. In air, the particles cannot travel more than a few centimeters. • Beta rays (P): Beta rays are streams of electrons. In air, the particles can travel several dozen centimeters in a zigzag...
