Description
Overview
GAOTek environmental radiation emanometer measure radon concentration in ambient air, soil and water and radon exhalation rate in soil and building materials. It can be applied in geological prospecting, radiation protection, nuclear accident monitoring, radiation dose assessment, earthquake prediction and teaching, etc.
Features
- Small size, light weight, suitable to carry
- High sensitivity, low power consumption, AC or DC double use
- With USB data transfer interface, equipped with a Bluetooth printer
