  Working Principles
Click to ViewGAMMA CHAMBER 5000 is a compact, portable, self, - shielded type of a Co-60 Gamma Irradiator. Its design conforms to American National Standards ANSI- N 4~3. L, 1977 for Safe design and use of self contained D1y Source Storage Garruna lrrad1ator (category - I). Atomic Energy Regulato1y Board (AERB), India, approves it as Type B (U) package for safety in transport of radioactive material. It also meets the IAEA regulations for tl1e safe transport of radioactive material as per safety series - 6, l 985(as amended in 1990). The Unit is designed to house 518 Tl3q (14000 Ci) of Cobalt-60 source and it provides An Irradiation volume of about 5000 c.c. Approximately. The doubly encapsulated sealed radioactive sources are used in cylindrical form, which are completely contained in a dry container called flask unit. The sealed sources are shielded at all times and human access to it and the volume undergoing irradiation is not physically possible in its designed configuration. The irradiation chamber is located in vertical shaft (Drawer). The shaft moves up and down with the help of a drive system, which enables exact positioning of the irradiation chamber in the center of the radiation field. Access holes of 8 mm diameter are provided in tl1e vertical shaft for introduction of service sleeves for gases, RTD censer etc. for temperature measurement inside irradiation zone.
