Brief technology description

• Tritium sources of soft beta-radiation (BITr-M)
  are the main component of developed eliminators.
  The sources represent a thin film (0,5 µm) made
  of titanium saturated with hydrogen
  isotope-tritium which is deposited on backing
  made of molybdenum. The working surface of the
  source is covered with the protective film made
  of silicon monoxide or dioxide.

• Tritium used in BITr-M is a pure beta-radiator
  which emits the lowest maximum energy (18,6 keV)
  among all known isotopes. It allows practically
  the unlimited use of the developed eliminators in
  production premises without taking special
  measures of radiation protection and in a number
  of cases these eliminators have no alternative.
• The operating principle of eliminators results in
  air ionization with electrons, irradiated by the
  sources and in the following interaction of
  charges in electrified materials with formed air
  ions of opposite polarity. Ionization current
  produced by BITr-M is 1,5.10-8 A/cm2.

5

• As a function of production conditions the
  different schemes of eliminator structure are
  possible. In one case the sources are set in
  proximity from electrifiable material (1-3 cm)
  and the ionization current is maintained owing to
  the electrostatic charge. The necessary value of
  ionization current from the working surface is
  provided by a choice of a set of BITr-M sources.
• The eliminators which meet the specific
  customer's requirements may be developed.
• The eliminator service life is no less than
• 8 years.

6
FIELDS OF APPLICATION

• The eliminators are used in chemical, textile,
  printing and other industrial branches
  manufacturing and retreating the film, sheet and
  powder materials which are electrized in the
  process of technological cycle.

7
Purpose

• They are designed to eliminate the electrostatic
  charge arising during the retreatment of highly
  electrizing materials. The use of eliminators
  allows to exclude the violation of technological
  process (material sealing, its crushing, the
  photomaterial exposure etc.) and to increase the
  work safety (excluding the probability of fires
  and explosions connected with spark formation,
  decreasing the value of electrostatic fields to
  safety levels etc.)
