Depleted Uranium slab Is a generic beta correction factor is assigned (such as 4 or 5) or is the specific value established during calibration assigned (such as 3.8)? A specific value is assigned at calibration for each instrument. Although typically for field measurement the generic value of 4.0 is used for ease of calculation and results in a conservative measurement.
