Typical Applications

Radiation monitors are multi-purpose digital instruments which are ideal for contamination and radiation detection. These monitors can be used for radiation monitoring on clothes and surfaces to research applications. They can also be used in the following areas:

  • Environment and home safety monitoring

  • Nuclear industry

  • Medical

  • Mining and metal industries

  • Border control, customs, cargo inspections


Are beta and gamma rays harmful?

Beta particles on the skin can cause burns and can be a serious direct or external radiation threat.

Gamma rays are ionising radiation and are biologically hazardous. They are harmful to humans as they can damage bone marrow and internal organs

How do you detect radiation?

Radiation monitors are used to detect radiation. Radiation is the by-product of radioactive decay. The main types of radiation are alpha, beta, gamma and x ray.
