1.5 Marking and sealing

1.5.1 A label should be attached to the products which constitute gamma-spectrometer with the

following designations:

designation of the product:

works number of product or unit according to the manufacturer's system of numeration;

year of production;

power consumption, voltage or current, power frequency;

degree of ingress protection provided by casings;

made in Russia.

1.5.2 Place and method of marking of the products which constitute gamma-spectrometer

should comply with the design documentation.

1.5.3 All products which constitute gamma-spectrometer should be sealed in accordance with

design documentation.

1.6 Package

1.6.1 Packaging meets the design documentation and provides protection against penetration of

atmospheric precipitation and aerosols, splashing water, dust, sand, solar ultraviolet radiation and

limits the penetration of water vapor and gases.

2 INTENDED USE

2.1 Operating limitations

2.1.1 Gamma-spectrometer shall be stationary installed in the laboratory room where normal

conditions of operation are ensured. There are no special requirements for the room where the gamma-

spectrometer is installed.

2.1.2 Scintillation detector unit with shielding shall be mounted in a location within a room

where the possibility of vibrations is minimal (closer to a corner or a wall of the room) and in a way

problems are excludes with connecting units to the wall outlets and to the protective earth terminals. It

is recommended to place the monitor so as not to expose its screen to the direct sun light and to ensure

protection in the place where the detector is located.

2.1.3 Gamma-spectrometer should be used in rooms where increasing of the natural

background is not possible.

2.1.4 Gamma-spectrometer has to be used in rooms where the presence of constant and/or

alternating magnetic fields with strength more than 40 A/m is excluded.

2.1.5 Qualified specialists – engineer-physicists and technicians (laboratory assistants) are

allowed to operate and perform maintenance of gamma-spectrometer. Those specialists shall be trained

in practical use of the Procedure manual for measurement of activity of radionuclides using the

scintillation gamma-spectrometer with software «Progress».

2.2 Preparation of the product for use

2.2.1 Assemble the shielding of the gamma-spectrometer and connect it to the protective earth

terminal. The assembly sequence is shown in the Appendix A.

Note – Sometimes connection of the protective earth can cause increasing of noise in the spectrometric channel. If

this is the case, check that all parts of the gamma-spectrometer are connected to the common ground loop.

2.2.2 Connect cable of the detector unit to the USB port of the personal computer in accordance

with the wiring diagram in the Appendix B. When connecting several detector units of the complex

«Progress» to the same PC, units are connected independent of each other to vacant USB ports. Use

USB splitter if necessary.
