What Are the Main Classifications of Radiation Dosimeters?

Radiation dosimeters are devices used to measure accumulated radiation dose or real-time radiation exposure for personal safety and environmental monitoring.

According to application and technology, radiation dosimeters are generally classified into the following categories:

1. Personal Radiation Dosimeters

Used by workers in nuclear plants, hospitals, laboratories, and industrial inspection areas to monitor individual exposure.

Examples include electronic personal dosimeters like the GM-300 by CESTSEN.

2. Area Radiation Dosimeters

Installed in fixed locations to continuously monitor ambient radiation levels in workplaces or public areas.

3. Passive Dosimeters

Such as TLD (Thermoluminescent Dosimeter) and film badges. These require later laboratory analysis and are commonly used for periodic dose records.

4. Electronic Real-Time Dosimeters

Digital devices that provide immediate dose rate readings, alarms, and data storage. These are increasingly preferred for modern radiation safety management.

GM-300 Personal Radiation Dosimeter Overview

The GM-300 Personal Radiation Dosimeter is an advanced electronic dosimeter developed by CESTSEN for real-time personal protection.

It is designed for users who need portable, accurate, and fast-response radiation monitoring in demanding environments.

The GM-300 is suitable for detecting:

-Beta (β) radiation
-Gamma (γ) radiation
-X-ray radiation

Why GM-300 Belongs to the Electronic Dosimeter Category

The GM-300 is classified as an electronic personal radiation dosimeter because it provides:

-Real-time radiation dose rate display
