gamma-irradiation of:

• Blood and blood derivatives
• Cell cultures
• Transplants

Gamma-irradiation prevents the partitionability of immunocompetent cells. The transmission of these cells, without irradiation, can cause serious and often mortal complications – Graft-versus-host-disease (GVHD) – for immunodeficient patients.

    exist in the scope of radiobiological research:

• In-vitro-analysis of radiosensitivity of peripheric and modulated blood cells
• Identification of histocompatibility via an analysis of the lymphocyte culture
• Analysis – after irradiation – of the molecular mechanism in the case of diseases which are connected with a defect of the enzyme system.

The self-shielded GSR C1 contains up to 3 Cs-137 sources with a maximum total activity of 120 TBq. The half-life period of Cs-137 is about 30,2 years.

The dose rate of < 5 μSv/h at the surface of the irradiation device is far below the regulated limit value.

     includes:

• Maintenance according to § 66 StrlSchV
• Dosimetry
• Control of medical electrical devices according to EN 62353 (DIN VDE 0751-1)

The user positions the irradiation good in the 3,8 l containing aluminium irradiation canister and puts it in the rotatable irradiation chamber. The complete closure of the door and the position of canister are checked automatically. The opening of the door is not possible during irradiation.

At the operator panel you set the irradiation parameters. After the manual starting of irradiation the irradiation drum rotates 180° and the canister is located directly in front of the radiation sources. Parallel, the electronic control starts the rotary motion of the canister with ca. 18 rpm. Thus a homogeneous dose distribution in the irradiation canister is guaranteed. After operation time the irradiation chamber drives into the starting position and the rotation of the canister is stopped. The door can be opened and the canister can be taken out.

The irradiation device is delivered in a licensed B(U) type transport packaging.

• Manual
• Dosimetry protocol
• Certificate of the radioactive source(s) with control of leak tightness
• Special form certificate
• 2 irradiation canisters

The installation inclusive dosimetry is accomplished by authorised
service technicians. Regarding the assembly a room
size of minimum 2,5 m x 2,5 m is required. The floor loading
is about 5,2 t/m².
