What role does ventilation play in handling radioactive substances?

Ventilation plays a crucial role in handling radioactive substances by helping to dilute and remove airborne radioactive materials from the environment. This is vital in maintaining a safer workplace, particularly in settings where radioactive materials are present. By ensuring an adequate flow of air, ventilation systems can minimize the concentration of radioactive particles and gases, thus reducing the risk of inhalation or contamination for workers.

In contrast, increasing humidity, enhancing visibility, and regulating temperature may have their own benefits in different contexts, but they do not address the primary concern of controlling exposure to airborne radioactive hazards. Effective ventilation specifically targets the control of these hazards, making it an essential component of safety protocols in environments that handle radioactive substances.
