BRIT has introduced GC 1200 in place of GC 900A. 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.However, BRIT will provide activity for GC900A for the benefit of those who had purchased the unit in the past.
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
