SHLD1 • Source holder

62092-EN-190704

The plant operator must appoint a radiation safety officer with the 

necessary expert knowledge. He is responsible for ensuring that the 

radiation protection ordinance is complied with and for implementing 

all radiation protection measures.
We offer appropriate training that imparts the necessary qualification 

in this field.
You can also find certified course providers on the homepage of the 

Federal Office for Radiation Protection: 

www.bfs.de

.

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

value. Only persons who undergo official dose monitoring are allowed 

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

for control areas in the radiation protection ordinance.
We are at your disposal for further information concerning radiation 

protection and regulations in other countries.

1.2  Appropriate use

When in operating mode, the source container SHLD1 described 

in this document contains a radiactive source for radiometric level, 

interface, switching and density measurement. The source container 

shields the radiation off from the surroundings and only allows it to 

exit, practically unhindered, in the direction of measurement.
To ensure the shielding effect and exclude damage to the radioactive 

source, all instructions in this operating instructions manual and the 

legal radiation protection regulations must be observed during instal-

lation and operation.
Operational reliability is ensured only if the instrument is used prop-

erly. We are not liable for damages caused by improper use.
You can find detailed information about the area of application in 

chapter "

Product description

".

1.3  Warning about incorrect use

Inappropriate or incorrect use of this instrument can give rise to 

hazards, e.g. risk to persons through exposure to gamma radiation. 

Damage to property and persons or environmental contamination can 

result. Also, the protective characteristics of the instrument can be 

impaired.
Take note of the respective safety instructions.

1.4  General safety instructions

This is a state-of-the-art instrument complying with all prevailing 

regulations and directives. The instrument must only be operated in a 

technically flawless and reliable condition. The operator is responsi-

ble for the trouble-free operation of the instrument. When measuring 

aggressive or corrosive media that can cause a dangerous situation 

if the instrument malfunctions, the operator has to implement suitable 

measures to make sure the instrument is functioning properly.
During the entire duration of use, the user is obliged to determine the 

compliance of the necessary occupational safety measures with the 

Radiation safety officer
