Applications of radiation

In public health care, radiation can be used to examine and treat patients. Examinations are X-ray or isotope examinations. In examinations or procedures that use radiation, care is taken to ensure that radiation exposure to the patient is kept to a minimum. In treating cancer, large doses of radiation are used to destroy diseased tissue. Read more about use of radiation in health care.

In industry radiation is used in several ways. For example in quality control of materials, measuring the level of containers, or monitoring the thickness or consistency of paper. Radiation is also used in non-destructive testing. Read more about use of radiation in industry.

Practical applications for non-ionising radiation are, among others, lasers, microwave ovens, solariums, mobile telephones, MRI devices in the medical field, and industrial heaters.
