Communicating about radiation to the public can be challenging. It's essential to use plain language and consider the audience's perspective to enhance understanding. Radiation is present in our environment, originating both naturally and artificially, from sources such as cosmic radiation and medical treatments. It’s crucial to explain the types of radiation, exposure pathways, and potential health effects clearly. By considering elements like time, distance, and shielding, we can address safety and health concerns effectively. This guide aims to improve discussions on radiation and its implications for public health.

EPR-Public CommunicationsL-02 Communicating Basics of Radiation
Challenge • Communicating with the public about radiation is challenging; • Communicate in plain language; • You will communicate better with people if you can think as they are thinking.
Sources • Radiation is naturally present in the environment. This is called natural background radiation; • People are exposed to natural radiation from outer space, the air, food and drink; • People may also be exposed to artificial radiation from medical treatment, consumer products and occupational exposure; • Often, medical exposures from diagnosis and in treatment account for the largest dose from artificial sources.

Effects of radiation • Deterministic: short term, occurring early after exposure; • Stochastic: long term, occurring years later.

Radiation protection • Time • Distance • Shielding
Am I safe? In addition to dose and dose rate quantities the following questions must be answered: • What was measured or reported? • How was the person exposed (exposure scenario)? • Who was exposed?
Potential health effects • Death; • Severe health effects (severe deterministic effects): • Severe burns; • Other non-fatal effects. • Health effects to foetus; • Cancer risk.
