Remarks

The Upward method of radon-removal is applied to the low-pass filtered data, using the formula: KRADREF = AK * URADREF + BK Output potassium background to remove (channel) THRADREF = ATH * URADREF + BTH Output thorium background to remove (channel) TCRADREF = ATC * URADREF + BTC Output total count background to remove (channel) UPURADREF = AU * URADREF + BU Output upward uranium background to remove (channel) where: AK = Input calibration factor ak (default: 0.8) BK = Input calibration factor bk (default: 0) ATH = Input calibration factor at (default: 0.1) BTH = Input calibration factor bt (default: 0) ATC = Input calibration factor atc (default: 12) BTC = Input calibration factor btc (default: 0) AU = Input calibration factor au (default: 0.25) BU = Input calibration factor bu (default: 0) and: URADREF = Output uranium background to remove (channel) where URADREF = (UPUFILT - A1*UFILT - A2*THFILT + A2*BT - BU)/ (AU-A1 - A2*AT) THFILT = Input Low-pass filtered thorium channel UFILT = Input Low-pass filtered uranium channel UPUFILT = Input Low-pass filtered upward uranium channel and A1 = Input Skyshine coefficient A1 (default: 0.036) A2 = Input Skyshine coefficient A2 (default: 0.022) Ref: See the RPSLEVLU.GXC file for details and implementation of the algorithm.
