Part Number	Description		Quantity
FHT770GR	Automatic 200mm sample changer

Please Note: Availability may vary by country.

Alpha/beta radioactivity in samples is measured with large area proportional counters. The alpha beta pseudo-coincidence technique compensates for the natural aerosol activity.

Extremely low detection limits for alpha emitters (e.g. Plutonium， Uranium) due to the very low alpha background of proportional detectors
Effective discrimination against artificial alpha/beta radioactivity using ABPD evaluation techniques natural Radon/Thoron progeny
Optional 50mm lead shielding available for low level beta measurement
Comprehensive Windows* software for measurements， reports， calibratio and functional test
FHT 8000 with embedded PC and special electronic is used for measurement
