RADGIL2 is an X-RAY irradiator specifically designed to prevent Transfusion Associated- Graft versus Host Disease (TA-GvHD), a rare but often fatal reaction caused by the donors’ Lymphocytes-T when grafted into a recipient with a transfused blood product. RADGIL2 is an effective, modern and safer alternative to the irradiators based on a nuclear source such as Caesium137. RADGIL2 is safe, easy to use and fast. Because the dose of ionizing radiation generated by the RADGIL2 can be easily adjusted, the machine can also be used for several research applications such as for the irradiation of:
