Fig. 3: Measures for protection against radioactive radiation

1 Shielding

2 Time

3 Distance

Shielding: Provide good shielding between the radioactive source

and yourself as well as all other persons. Special source containers

(e.g. VEGASOURCE) as well as all materials with high density (e.g.

lead, iron, concrete, etc.) provide eective shielding.

Time: Stay as short a time as possible in radiation exposed areas.

Distance: Your distance to the source should be as large as possible.

The local dose rate of the radiation decreases in proportion to the

square of the distance to the radiation source.

The plant operator must appoint a radiation safety ocer with the

necessary expert knowledge. He is responsible that the radiation

protection ordinance is maintained and that all radiation protection

measures are implemented.

Control areas are areas in which the local dose rate exceeds a certain

value. Only persons who undergo ocial dose monitoring are allowed

into these control areas. You can nd the respectively valid limit values

for control areas in the guideline of the respective authority (in Ger-

many, for example, the radiation protection ordinance).

We are at your disposal for further information concerning radiation

protection and regulations in other countries.
