Horiba PA-1000 Environmental Radiation Monitor Radi
Measurement can be easily made only by injecting the extracted water sample into the attached cell and setting it to the equipment
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
Features
- Easy measurement by Anyone, Anytime, Anywhere
- Designed with plant-based plastic material helping to reduce petroleum consumption
- 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)

Resources
Types of radiation
- Alpha rays (α): 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 (β): Beta rays are streams of electrons. In air, the particles can travel several dozen centimeters in a zigzag pattern.
- Gamma rays (γ): Gamma rays, the most penetrating type of radiation, are electromagnetic waves. They can pass through the human body. X-rays that are used in X-ray machines are also electromagnetic waves.
Radiation units
- Becquerel (Bq): The becquerel (Bq) is the unit of radioactivity. The radioactivity of a substance measured in becquerels is the number of its nuclei that decay each second.
- Gray (Gy) and Sievert (Sv): These units express the effect of radiation. The gray expresses the amount of radioactive energy received, while the sievert expresses the effect on a human being. Normally the gray and the sievert are used to express quantities per hour; the units are Gy/h and Sv/h, respectively.
