AMS02T Aerosol Monitoring (Tape Filtration) System

Aerosol Monitoring (Tape Filtration) System

Product introduction           

• AMS02T for the measurement of radioactive aerosols, especially man-made nuclides AMS02T is a tape-type filter membrane sampling device of the AMS series Bitt technology.

• AMS02T is a stepping belt filter device. The stepping belt unit is characterized by ease of use, maintenance-free mechanics and high nuclear sensitivity. Device measures Alpha, Beta, Gamma Aerosol, Essential Iodine and Beta in one unit

inert gas.

• AMS02T has one or two or three radiation detectors. Alpha and Beta (Radon) measurements are made using a glass fiber filter using a single detector system, embedded PIPS detector.

• In a dual detector system we additionally built 'NaI(Tl)' scintillation detectors or LaBr3(Ce) scintillation detectors for aerosol gamma and basic iodine measurements. The third detector can measure beta noble gases with a plastic scintillation detector. The device has two filter belts. The upper part is a 60 mm wide fiberglass belt for collecting aerosols and the lower part is a 60 mm wide activated carbon impregnated (charcoal) filter belt for adsorption of inorganic iodine. The iodine filter band can be removed separately.
