CS Gamma Irradiation Chamber

The Gammacell GC40 is mainly used for irradiating cells or small animals to induce radiation damage, e.g. for studying DNA damage response and radiation-induced repair processes.

The GC40 irradiator allows to treat biological material with γ-radiation at a dose rate (as of March 2016) of  ~ 0.78Gy/min. So, if planning experiments it is important to calculate the irradiation time for the sample accordingly. Instructions on how to do this are provided upon the compulsory introductory and the yearly radiation safety instruction. A set of 3 attenuators are built in to reduce the central dose rate within the GC 40 sample chamber by 33, 60 or 80%, respectively. In addition, the GC40 collimator allows for reducing the central dose rate by 95%.

The GC40 has a microprocessor-based control system that allows the user to operate the unit easily, safely, and efficiently through the control panel (keypad and display).

The GC40 team provides introductions into safe usage of the GC40 for FLI researchers as well as for external users.

Through annual maintenance (service by GC40 supplier and TÜV), safe operation and use is ensured.
