3. DESCRIPTION OF PROGRAM OR FUNCTION

RADCOMPT automates gross alpha  and gross beta sample analysis calculations and, in many cases, warns the technologist when a hazard level is being approached or when it has been exceeded. The RADCOMPT program is unique in that it corrects for crosstalk between channels, and in this way provides increased accuracy and efficiency. Even though it is designed explicitly for the analyses of air samples and wipe samples, it can  also be used for other sample types. It is designed to be used with  a dual channel counter (in which one channel is used for alpha detection and the other for beta detection), but may be used with two single channel counters employed for the same purpose. In addition, it provides an automated means for the execution of the following radiological sample analyses protocol:

A. Calibration of the counting system

B. Calculation of sample activity or air activity concentrations (with the activities of air activity concentrations at the top and bottom of the two-sided 95 percent confidence interval also specified).

C. Determination of minimum sample counting times required for detection and/or quantification of specified alpha and beta activities or air activity concentrations. In addition, alternate counting times are determined for alternate activities such that the specified alpha and beta activities are at the top of the 95% confidence interval, increasing the confidence that the activities measured are below the specified limits.

D. Calculation of the minimum detectable activities or air activity  concentrations.

E. Determination of air sample volumes required for detection and/or quantification of specified alpha and beta air activity concentrations.

F. Calculation of long-lived activities or air activity concentrations based on radon daughter and thoron daughter decay.

G. Calculation of employees DAC-Hours and estimated Committed Effective Dose Equivalent.

H. Varying calibration constants (to coincide with possible adjustments to the counting system) to help optimize the calibration of the counting system.

4. METHOD OF SOLUTION

The crosstalk correction is performed via simple derivation as described in the manual. The long-lived activity calculations use methodology derived from reference C (below). The statistical error calculations use techniques derived from the references noted as background information.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

RADCOMPT is NOT designed to be used with an alpha ONLY or beta ONLY counting system. It is designed to be used with a dual channel counter (in which one  channel is used for alpha detection and the other channel is used for beta detection), or with two single channel counters employed for the same purpose.

13. OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED

Borland Turbo C++ v1.01 was used to create executables in package.
RADCOMPT will run either within the MS-DOS environment or within MS  Windows 3.0 or above (utilizing MS-DOS emulation). When MS Windows is utilized, several copies of the RADCOMPT program may be run simultaneously on the same computer, with each copy corresponding to a different counter (when each copy of the RADCOMPT program is run from a different directory on the hard drive). Installation instructions may be obtained by activating the "INSTALL.BAT" file by typing "INSTALL" and pressing the Enter key.
