Table 1-4
Gamma Rays/X-Rays
No mass.
No charge.
Electromagnetic wave or photon.
Physical
Similar (difference is the place of origin).
Characteristics
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.
Range
Concrete.
Water.
Lead.
Shielding
Whole body exposure.
The hazard may be external and/or internal.
This depends on whether the source is
inside or outside the body.
Hazard

4. Neutrons
a.
Physical characteristics
1) Neutron radiation consists of neutrons that are ejected from the nucleus.
2) A neutron has mass, but no electrical charge.
3) An interaction can occur as the result of a collision between a neutron and a nucleus.
The nucleus recoils due to the energy imparted by the neutron and ionizes other atoms.
This is called "secondary ionization."
4) Neutrons may also be absorbed by a nucleus. This is called neutron activation. A
charged particle or gamma ray may be emitted as a result of this interaction. The
emitted radiation can cause ionization in other atoms.
b. Range
1) Because of the lack of a charge, neutrons have a relatively high penetrating ability and
are difficult to stop.
