  • Page 5: For Your Safety

    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. SHLD 1 • Source holder...

  • Page 6: Appropriate Use

    We are at your disposal for further information concerning radiation protection and regulations in other countries. Appropriate use When in operating mode, the source container SHLD 1 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.

    Article number - Documentation • Note: "Highly radioactive source" (if necessary) The serial number allows you to access the delivery data of the instru- ment via "www.vega.com", "VEGA Tools" and "Instrument search". Note: The local dose rate stated on the type label at a defined distance is safety-oriented and includes production-related fluctuations of the emitters as well as tolerances of the measuring instruments. There can thus be deviations in the local dose rate calculated with the speci- fied attenuation factors. See also "Principle of operation/Source".

    Cs-137. The radioactive source in the source container emits gamma rays. The SHLD 1 is mounted on the vessel, the pipeline or on a conveyor belt/spiral conveyor directly opposite the sensor. The source container shields the environment against gamma radia- tion and protects the radioactive source against mechanical damage or chemical influences. In case of large measuring ranges (e.g. with...
