What type of radiation source would require regular monitoring according to safety standards?

Gamma radiation sources necessitate regular monitoring due to their ability to penetrate materials and the potential for serious health risks associated with exposure. Gamma radiation is highly energetic and can travel considerable distances, meaning individuals working near these sources can be exposed to harmful levels of radiation even from afar. Monitoring ensures that exposure stays within established safety limits and allows for immediate response if radiation levels exceed safe thresholds.

In contrast, ultraviolet, infrared, and visible light sources predominantly operate at energy levels significantly lower than gamma radiation, and their health risks are generally related to thermal effects or skin and eye damage rather than ionizing radiation. These types of light typically do not require the same level of stringent monitoring as gamma radiation sources, making it essential to focus monitoring efforts on those with the highest potential for harm.
