MODULE 16- RADIATIONSAFE COMPANY

IONISING RADIATION IIonising radiation can change cells within a substance! But it has also useful functions and a very energetic value.

• Types: alpha, beta and gamma radiation

• Radioactive substances emit ionising rays. Strength depends on the radioactive substance type and the distance from the source.

• Not always result of human actions. Some natural materials emit spontaneous ionising radiation.

IONISING RADIATION II• Risks: Radiation can damage cells.

• General measures: as much distance as possible (perimeter), reducing exposure duration, radiation source must be protected, work permits and warning signs.

• Professional exposure: employees must carry a dosimeter (constant measures and registers), rotation, regular medical examinations, radiation specialists in work place.

NON-IONISING RADIATION Non-ionising radiation can enter skin and/or eyes causing harm!

• Ultraviolet radiation: Employees working outdoors. Acute (burning) or chronic risks (skin cancer).

• Protection: appropriate clothing, sunglasses and sun oil.

• Infrared radiation: Risks for skin (burning) and eyes (cataracts, retinal burns).

• Protection: protective clothing, protective glasses or goggles.
