A comprehensive system of principles, practices, and protocols designed to protect people and the environment from harmful effects of ionizing and non-ionizing radiation.

Overview

Radiation safety encompasses the methods, procedures, and guidelines implemented to minimize exposure to harmful radiation while enabling beneficial uses of radioactive materials and radiation-producing devices. This field integrates principles from nuclear physics, health physics, and occupational safety to create robust protection frameworks.

Core Principles

The fundamental pillars of radiation safety follow the ALARA principle (As Low As Reasonably Achievable):

Time: Minimizing exposure duration
Distance: Maintaining maximum practical distance from sources
Shielding: Using appropriate barriers to block radiation

These principles work in conjunction with dosimetry monitoring and strict regulatory compliance.
