Module 1: Radiological Fundamentals
2) The range in air is very far. It will easily go several hundred
Gamma/X-ray radiation is best shielded by very dense materials,
such as lead. Water or concrete, although not as effective as the
same thickness as lead, are also commonly used, especially if the
thickness of shielding is not limiting.
d. Biological hazards
Gamma/X-ray radiation can result in radiation exposure to the
(Insert facility-specific information.)
Electromagnetic wave or photon.
Similar (difference is the place of origin).
Range in air is very far.
It will easily go several hundred feet.
Very high penetrating power since it has no
mass and no charge.
Whole body exposure.
The hazard may be external and/or internal.
This depends on whether the source is inside
or outside the body.
