GEOTEST a Fortran 77 program for a geothermal well tracer injection test

As part of the computerization project of the Industrial Applications Division, a computer program in Fortran 77 has been written for geothermal well-tracer injection test calculations. It classifies whether or not a radioactivity count obtained is significantly above background count and construct the breakthrough curve, a graph of corrected significant net sample count versus the corresponding time elapsed from the date of injection of the tracer. Actual and fabricated data representing different monitoring schemes were imputted to the computer and the results were determined to be correct. (author)
