4.3.2.6 Ultraviolet (UV) waves, alpha, beta and gamma rays can have hazardous effects on human body tissue. The effects depend on the type of radiation and the size of the dose. Radiation dose (in Sieverts) is a measure of the risk of harm resulting from an exposure of the body to the radiation. Ultraviolet waves, X-rays, alpha, beta and gamma rays are all examples of ionising radiation. They can turn atoms into ions and break up molecules. Ionising radiations can change DNA, causing mutation of genes that may lead to cancer. High energy gamma rays can be used to destroy cancer cells. Describe and explain the effects that gamma, X-rays and ultraviolet radiation have on the body. Explain how the radiation dose that nuclear industry workers are exposed to is measured. Describe how high energy gamma rays can be used to destroy cancer cells. 1 Explain how the radiation dose that nuclear industry workers are exposed to is measured. Explain how a radiation badge detects radiation. Draw conclusions from data about the risks and consequences of exposure to radiation. Describe how ultraviolet radiation from the sun can affect the body and in particular the skin. WS 1.5 Interpret simple measures of risk showing the probability of harm from different types of radiation. WS 1.5 Describe precautions that can be to reduce the risks from ionising radiation. WS 1.5 Is radiation harmful? Does sunbathing cancer? Are sunbeds than sunbathing? How can I reduce the risk of skin cancer? Do people working in a nuclear power station have a greater risk of cancer? Research the radiation dose level people in various professions are exposed to (eg nuclear industry, pilot, science teacher). Plan an investigation to find out which sunscreen is the most effective – probes are available for data loggers to measure the intensity of ultraviolet light. rays,
