BRIT has launched a new Cs-137 based Blood Irradiator.Irradiation of blood & blood products by gamma rays is a proven and safe method to inhibit T-Lymphocyte Proliferation and eliminate the risk of post transfusion graft versus host disease (T-GVHD).
Gamma irradiation of cellular blood components is the best current technology to reduce the risk of T-GVHD to the recipients as confirmed by research and therefore being widely practiced world over in hospitals and blood banks as a life saving approach to this problem. Blood is usually irradiated in standard blood bags in dedicated blood irradiators using cobalt-60 or caesium-137 radioactive source. The usual recommended radiation doses are 25 Gy to 35 Gy (1 Gy = 100 rad) for this purposes.
BRIT has designed and developed a dedicated blood irradiator called Blood Irradator-2000 (Bl-2000. It is a self-shielded, compact and versatile Gamma Irradiator which can house cobalt-60 source upto 25 TBq (675 Curies).
It provides a dose rate ofabout 11 Gy/minute approximately inside the sample chamber. It is incorporated with a sample rotating mechanism to obtain better uniformity of dose to the products. The control system is PLC (Programmable Logic Controller) based with touch sensitive color screen using user-friendly software and a printer for data recording.
The unit can be installed in a room without any additional shielding. Its design conforms to all relevant national and international standards and safety codes. It meets the requirement of Type B(U) package for transportation.
BRIT will undertake servicing and source replenishment whenever required. Source Disposal: BRIT will also take up source disposal as and when required.
