What is a Survey meter?

A survey meter is a portable device used to measure radiation levels. It typically employs Geiger-Müller tubes or scintillation detectors to easily detect and measure radiation levels in the environment. Survey meters are widely used in various fields such as radiation work sites, nuclear facilities, detecting abnormalities outside radiation control zones, and radiation monitoring during emergencies.

These devices can usually measure gamma rays, beta particles, and alpha particles, and some models are capable of detecting neutron radiation. Due to their lightweight and portable design, survey meters are ideal for checking individual radiation exposure or measuring radiation levels across larger areas. The data obtained from survey meters serve as critical indicators for ensuring radiation safety standards and supporting prompt decision-making on-site.

Application of Survey meter

１．Safety Management at Nuclear Facilities
Survey meters are used in and around radiation control areas at nuclear power plants or research facilities to ensure worker safety. If abnormal radiation levels are detected, quick action can be taken.
２．Radiation Monitoring in Medical Facilities
In medical facilities performing radiation therapy or X-rays, survey meters are used to regularly check for radiation leakage and workplace radiation levels. They also aid in monitoring exposure for medical staff.
３．Disaster Monitoring
During nuclear disasters, survey meters are used to measure radiation levels in evacuation zones and assess contamination levels. This helps reduce exposure risks for affected populations.
４．Inspection of Industrial Waste
To ensure safety, survey meters are employed to measure radiation levels in industrial waste that may contain radioactive materials before transportation or disposal.
