Radiation and Children's Health
Executive Summary
Highlights
Radiation (the emission of energy as electromagnetic waves or particles) can disrupt molecular structures, directly damaging people's DNA and increasing their risk of cancer and other health conditions. Children are more sensitive to radiation than adults due to several physiological, anatomical, developmental, and behavioural factors. Because their cells replicate more frequently, children are more vulnerable than adults to DNA damage from ionizing radiation. Moreover, children’s smaller body size means they absorb a higher dose of radiation per unit of body mass compared to adults. Certain organs, such as the thyroid, are particularly sensitive. The ALARA (As Low As Reasonably Achievable) principle is critical in minimizing unnecessary medical radiation, particularly in diagnostic imaging. Parents can encourage sun-safe behaviours such as wearing protective clothing, applying broad-spectrum sunscreen, protecting the eyes, and limiting outdoor activities during peak UV hours. Families can encourage prudent use of digital devices, emphasizing limited screen time and maintaining physical distance from EMF sources, particularly for young children.
