GAMMA CHAMBER 5000
Gamma Chamber 5000 is a compact self shielded cobalt-60 gamma irradiator providing a dose rate ca. 6 kGy/h (03.2012) and have an irradiation volume of approximately 5000cc. The size of sample chamber 17.2cm (dia) X 20.5cm (ht). The material for irradiation is placed in an irradiation chamber located in the vertical drawer inside the lead flask. This drawer can be moved up and down with the help of a system of motorised drive which enables precise positioning of the irradiation chamber at the centre of the radiation field.
Two access holes of 8 mm diameter are provided in the vertical drawer for introduction of service sleeves for gases, thermocouple, etc (on the picture you can see heating apparatus under computer control). A mechanism for rotating/stirring samples during irradiation is also incorporated. The lead shield provided around the source is adequate to keep the external radiation field well within permissible limits. The unit can be operated manually, but for routine operation built-in timer provides accurate control of irradiation time from 6 seconds onwards.
The design of Gamma Chamber conforms to American National Standards, ANSI-N433.1-1977 for safe design and use of self-contained dry source storage gamma 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.
