Statistics 
 chisquared.xls
Calculate chisquared for a number of counts to check that the statistical variablility is satisfactory. Includes a chisquared graph, on which the calculated chisquared is plotted.
 WeightedMean.xls
Calculate, and compare, simple and weighted means.
 ztestcomparison.xls
Compare measured values against reference values to assess the concordance of the measured data. Useful for an initial check of your NPL Intercomparison results.

Decay 
 atomicmasses.xls
A complete list of atomic masses, together with the opportunity to calculate decay energies and assess the likelihood of decay by the different decay modes.
 decay.xls
Plot single and composite decay curves  just for interest!
 parentdaughterdecay.xls
Calculate the combined activity of a parentdaughter combination, together with the equilibrium activity ratio.

Calibration 
 FWHMMultifit.xls
Compare linear, quadratic, Debertin and Helmer and squareroot quadratic fits to FWHM data. (See the inadequacies of the Canberra Genie equation. (The spreadsheet comes loaded with the pooled data from 27 varied calibrations.)

NORM Analysis 
 NORMconsistency.xls
Paritions the 186 keV peak between 235U and 226Ra and corrects for certain spectral infererences and then checks all results for consistency. If there is disequilibrium, or to a limited extent nonnatural uranium isotopic abundance, allows measurements to be combined in such a way as to take that into account.

Detector Characterization 
 detectorspecificationcheck.xls
After measuring a ^{60}Co spectrum under standard conditions, calculate compare resolution, peaktoCompton and relative efficiency with the specification values.
 FitGaussiantoPeak.xls
Take a real spectrum peak, put the channel contents into the spreadsheet and fit a Gaussian and, if necessary a continuum step.
 MDADetectorcomparison.xls
Compare two detectors in terms of resolution and relative efficiency. Get some feeling for the way in which altering these and other parameters alters the MDA  usually, not greatly!
 randomsummingcorrection.xls
Using the twosource method, calculate the random summing correction factor for insertion into your spectrum analysis program.

System Throughput

 colltimevsize.xls
Calculation of charge collection time as a function of detector size, in terms of relative efficiency.
 throughputcalculations.xls
Calculation of system throughput as a function of shaping time and other related parameters according to the equations in Chapter 14. Examples of fitting the model to actual throughput data for analogue and digital systems are included.

Miscellaneous 
 voightfunction.xls
A plot of the Voight Function compared to the Gaussian and Lorentzian functions. Just for interest.
 TCS Estimation
Assess the degree of summing on your own detector. (Point source model only.)
