Some Useful Information Concerning the results:
The Conversion factors for the primordial nuclides are given by:										1 Bq 238U/kg = 81 ppb U (81 x 10-9 gU/g)						The 238U decay chain gammas used are:						234Th: 63.29 and 92.59 keV 226Ra: 186.1 keV
																						214Pb: 295.21 and 351.92 keV
																						214Bi: 609.31, 1120.29, 1764.49 and 2204.21 keV
The relationships are valid for any daughters in the 238U, 235U or 232Th chain only if the chain is in equilibrium.										1 Bq 232Th/kg = 246 ppb Th (246 x 10-9 gTh/g)						The 232Th decay chain gammas used are:						212Pb: 238.63 and 300.09 keV
																						208Tl: 277.371, 583.19, 860.557 and 2614.53 keV,
																						228Ac: 209.253, 338.320, 463,004, 911.21, 964.766 and 968.971 keV
										1 Bq 40K/kg = 32300 ppb K (32300 x 10-6 gK/g)						The 40K decay chain gamma used is:						40K: 1460.83 keV
										1 Bq 235U/kg = 1.76 ppm U (1.76 x 10-6 gU/g)						The 235U decay chain gammas used are:						235U: 143.76, 163.33 and 205.31 keV
Background runs for the Well Detector
If a measurement in the signal region is below the sideband regions then the 90% confidence limit is calculated.
