2.1 Authorised personnel
All operations described in this documentation must be carried out
only by trained and authorized personnel.
During work on and with the device, the required personal protective
equipment must always be worn.
The handling of radioactive substances is regulated by law. The radia-
tion protection rules of the country in which the system is operated
applyrstandforemost.
In Germany the current radiation protection ordinance (StrlSchV)
based on the Atomic Energy Law (AtG) is applicable.
The following points are important for measurement with radiometric
methods:
A handling permit is required for operation of a system using gamma
rays.This permit is issued by the respective state government or
theresponsibleauthority(ocesforenvironmentalprotection,trade
supervisory boards, etc.)
We would be pleased to assist you in applying for the permit.
Whenhandlingradioactivesources,unnecessaryradiationexposure
mustbeavoided.Anunavoidableradiationexposuremustbekeptas
low as possible.Take note of the following three important measures:
1 2 3
Fig. 1: Measures for protection against radioactive radiation
1 Shielding
2 Time
3 Distance
Shielding: Provide good shielding between the source and yourself
as well as all other persons. Special source containers 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 radioactive source in the source container emits gamma rays.
The VEGASOURCE 82 is mounted on the vessel or the pipeline
directly opposite the sensor.
The source holder shields the environment against gamma radia-
tion and protects the radioactive source from mechanical damage or
chemicalinuences.Incaseoflargemeasuringranges(e.g.withhigh
vessels) two or more source holders are used.

The rays emitted by the gamma source are damped when penetrat-
ing the medium. The sensor detecting the attenuated radiation on the
opposite side of the vessel calculates the measured value from the
intensity of the radiation.

We are only allowed to ship radioactive sources when we have a copy
of the handling permit in hand. We can assist you with the procure-
ment of the necessary documents. If you need help, contact our
responsible sales organisation.
For safety reasons and to save costs, we always ship the source
holder with the source installed. If the operator needs the source
holder in advance, the source has to be shipped separately at a later
time. In such cases, the source is shipped in a transport drum.
Other countries
We are only allowed to ship radioactive sources when we have a copy
of the import license in hand. We can assist you with the procurement
of the necessary documents. If you need help, contact our responsi-
ble sales organisation.
We can only ship to foreign countries when the radioactive source is
mounted in the source holder.
During shipment, the source holder is in switch position " OFF". This
position is secured by a lock.
