BRIT has introduced
GC 1200 in place of GC 900A. However, BRIT will provide activity for GC900A for the benefit of those who had purchased the unit in
the past.
GC
1200
It's design conforms to American National Standards,
ANSI-N433.1-1977, as well as requirements of type B(U) package for safety in transport of radioactive materials as
per AERB code No.SC/TSR-1, 2000 of Atomic Energy Regulatory Board of INDIA. |
|
|
Features : |
-
Safe
and self-shielded: The shielding provided is adequate to limit
the radiation field on the external surface of the unit, well within
the permissible levels. No additional shielding is required for its
installation and use.
-
Automatic
control of irradiation time: Built-in timer provides accurate
control of irradiation time from 6 seconds onwards. The unit can also
be operated manually. Solid state programmable controls have been
provided. In the event of power failure battery backup displays the
programmes.
-
Manual
control of irradiation temperature: It is possible to irradiate
samples at low or high temperature by circulating liquid nitrogen
or hot air. These can be introduced through the service sleeves provided
in the vertical drawer. The irradiation temperature is sensed by a
thermocouple and displayed on the panel.
-
Dose
uniformity: Stationary source pencils, symmetrically placed in
a cylindrical cage ensures good uniformity of radiation field in the
sample chamber. In addition a mechanism is also provided for rotating/stirring
samples during irradiation.
-
Easy
loading and unloading of samples: Sample chamber extends to a
convenient height for easy loading and unloading of samples.
-
Safety
assurance: The design of Gamm Chamber conforms to American National
Standards, ANSI-N433.1-1977 for safe design and ue of self-contained
bry source storage gamm irradiators(Category I). It also meets the
requirements of type B(U) package for safety in transport of radioactive
materials as per AERB code No.SC/TR-1, 1986 of Atomic Energy Regulatory
Board of INDIA |

Gamma
Chamber is a versatile equipment for research studies in many fields such as: |
- Attenuators to bring down the radiation dose in the sample chamber
by 25% or 50% - are available on request.
- Ceric-cerous dosimeters are available in sets of 100 ampules of
2 ml. The Kilo Gray Gamma Dosimeter system to read out the dose delivered,
is also available.
- Biological indicators inoculated with 106 - 107 spores of Bacillus
Pumilus ATCC 14884, on paper disc are available in multiples of
100 numbers (50 pairs). These are useful when sterility is to be construed
without subjecting the sample to destructive sterility test.
