RADIATION HAZARDS

RADIATIONS

¡  Radiation is energy that comes from a source and travels through some material or through space in the form of waves.
¡  Light, heat and sound are types of radiation.
   SOURCES OF RADIATION
¡  Natural Radiation
    Includes solar and cosmic radiation, radiation emitted from the earth's crust and internal radiation from the foods we eat and drink. 
¡  Man-Made Radiation 
    Includes medical (x-rays and diagnostic materials), industry, consumer products (such as smoke detectors and television sets), and atmospheric testing of nuclear weapons.
¡  Radiations are of two types
v  Non Ionizing Radiations
v  Ionizing Radiations
IONIZING RADIATIONS
   Ionizing radiation causes some of the atoms it strikes to be ionized. There are several different types:
¡  Alpha
¡  Beta
¡  Gamma
¡  UV
¡  X-rays
NON-IONIZING RADIATIONS
Non-ionizing radiation, which does not ionize atoms
It includes
  • Infrared radiations
  • Radio waves
  • Microwaves
NON-IONIZING RADIATIONS
Non-ionizing radiation, which does not ionize atoms
It includes
  • Infrared radiations
  • Radio waves
  • Microwaves
  •       IONIZING RADIATIONS
  • They are heavy, very short-range particles and are actually ejected helium nucleus.
  • Can be stopped by paper or skin (epidermis).
  • Alpha radiation is not able to penetrate clothing.
  • Alpha-emitting materials can be harmful to humans if the materials are inhaled, swallowed, or absorbed through open wounds.
HAZARDS OF ALPHA RADIATIONS
¡  Because alpha radiation loses energy rapidly, it doesn’t pass through skin.
¡  It is not a hazard outside of the body.
¡  If eats or drinks something containing alpha radiation or breathes it in, the radiation can be harmful.
¡   Over a long period of time, and at elevated levels, radium increases one’s risk of bone cancer and uranium increases one’s risk of kidney damage.

¡ IONIZING RADIATIONS
¡  Gamma radiation are highly penetrating electromagnetic radiation.

¡  Gamma radiation are able to travel many feet in air and many inches in human tissue. They readily penetrate most materials and are sometimes called "penetrating" radiation.

¡  Dense materials are needed for shielding from gamma radiation. Clothing provides little shielding from penetrating radiation.
X-radiations
¡  X-radiation are shorter in wavelength than UV rays and longer than gamma rays.
¡   They are also called Rontgen radiation, who is usually credited as its discoverer, and who had named it X-radiation to signify an unknown type of radiation.
