The BH3206 type alpha and beta surface contamination measuring instrument is mainly used for measuring alpha and beta radioactive contamination on surfaces such as environmental radiation, nuclear power plants, isotope production, hospitals, reactor sites, clothing workstations, and floors. Composed of a detector, control panel, and printer. Can simultaneously measure the total surface alpha and total beta counts of pollutants; The measurement results can be stored in the microcontroller, printed on site, or input into a computer for printing.

One measurement can display the total surface alpha and beta particle count (CPS) of pollutants after deducting the background, and provide corresponding errors.
