# Radiation Exposure

[Resources](https://www.australiawidefirstaid.com/resources) › [Glossary](https://www.australiawidefirstaid.com/resources/glossary)

## What is Radiation Exposure?

Radiation exposure occurs when an individual is exposed to ionizing radiation, which can damage cells and increase the risk of cancer.

Radiation exposure refers to the absorption of harmful ionizing radiation by the body, which can occur during accidents involving radioactive materials, medical procedures, or environmental sources.

Ionizing radiation can damage cells and tissues, leading to acute radiation syndrome (ARS) or long-term health effects such as cancer. Responders encountering individuals exposed to radiation must prioritize safety by limiting their exposure and following established radiation protection guidelines.

Initial response involves assessing the casualty for signs of radiation exposure, including nausea, vomiting, and skin burns. Decontamination procedures may be necessary to remove radioactive particles from the casualty's clothing and skin. Emergency medical services should be contacted promptly for further assessment and treatment. Responders trained in radiation safety protocols play a crucial role in minimising health risks and ensuring appropriate care for those affected.

## First Aid for Radiation Exposure

1. Remove from Source: Get the casualty away from the source of radiation.
2. Remove Contaminated Clothing: Carefully remove clothing and seal it in a plastic bag.
3. Wash Exposed Skin: Use soap and water to clean the skin thoroughly.
4. Seek Medical Help: Contact emergency services for further evaluation and treatment.
