2.8 General instructions on radiation protection
When working with radioactive sources, avoid any unnecessary exposure to radiation. All
unavoidable radiation exposure must be kept to a minimum. Three basic concepts apply to
achieve this:
A
B C
A0016373
A Shield
B Time
C Distance
2.8.1 Shield
Ensure the best possible screening between the radiation source and yourself and all other
persons. Source containers (e.g. FQG60, FQG61, FQG62, FQG63, FQG66) and all high-
density materials (lead, iron, concrete) can be used for effective screening purposes.
2.8.2 Time
The time spent in the exposed area should be kept to a minimum.
2.8.3 Distance
Keep as far away from the radiation source as possible. The local radiation dose rate
decreases in proportion to the square of the distance from the radiation source.
2.9 Legal regulations for radiation protection
The handling of radioactive emitters is legally controlled. The radiation protection
regulations of the country in which the plant is operated are of overriding importance and
must be strictly observed. In the Federal Republic of Germany, the current versions of the
Radiation Protection Act and the Radiation Protection Directive apply. The following points
derived from this Ordinance are particularly important for radiometric measurement:
2.9.1 Handling permit
A handling permit is required by the operator of a plant that uses gamma radiation. Permit
applications are made to the local state government or the authority responsible (State
Offices for Environmental Protection, Trade Inspection Offices, etc.). The Hauser
sales organization will be happy to help you obtain the handling permit.
