When the body is exposed to large doses of ionising radiation over a short period, for example as a result of a radiation accident – can lead to severe massive cell destruction and death of the person.
DAMAGE TISSUE AND ORGANS
A cell damaged by ionising radiation can lose its ability to control the rate at which it reproduces – this is cancer. Radiation damage to tissue and/or organs depends on the dose of radiation received, or the absorbed dose.
GENETIC DEFECTS & REPRODUCTIVE TOXICITY:
Damage to genetic material in reproductive cells can cause genetic mutations that can be passed on to future generations.
Clouding of the lens of the eye, eventually leading to blindness.
Effects on the production of bone marrow resulting in a reduction of white blood cells and a less effective immunity system to fight infections.
NERVOUS SYSTEM EFFECTS:
Alteration of the electrical activity of the brain resulting in headache, fatigue, dizziness, changes in behaviour.
CARDIO-VASCULAR EFFECTS: Altered blood pressure; altered electrical activity of the heart.
The impact of exposure to radiation in the workplace is that everybody is exposed to varying low levels of natural radiation as part of daily life.
Radioactive materials, such as the radioactive waste from power stations, can be a real health hazard.
