3 Liter Radiation Monitoring Chamber Type 34031

The 3 liter chamber is used as a stationary surveillance device for environmental radiation monitoring. The chamber is designed to measure protection level dose rates. The chamber is guarded up to the sensitive volume. Since the sensitive volume is open to the surroundings, air density correction is required for precise measurement. The cylindrical chamber is made of graphite coated polyethylene with 4 mm wall thickness. The ion-collecting electrode is made of graphite coated, too. The external chamber diameter is 150 mm and the length is approx. 200 mm. For the transfer of the measuring signal and the polarizing voltage, the chamber is supplied with two coaxial connectors. The maximal chamber polarizing voltage is 1000 V. The chamber is supplied with an integrated adapter for positioning a radioactive check source of type T48010, which makes it possible to check the proper performance of the entire measuring system.

• Vented sensitive volume of 3 liters
• Suitable as radiation monitoring chamber
• Gamma energy range 80 keV to 1.3 MeV
