5.0 PROCEDURE
NOTE - Sections 5.1 through 5.5 in this procedure may be performed and/or re-performed in
any logical order or not at all as directed by CRFLM.
- The Tennelec Series 5 XLB system shall be used only to measure and report alpha and
beta radiations for samples in accordance with approved procedures and system
calibration.
- At various points in this procedure the technician is directed to enter a Sample Log
Number into the computer and/or analysis report. For the purpose of sample tracking,
it is necessary to use the Sample Log Number rather than the sequential file number
provided by the software.
5.1 System Power and Gas Supply
Special Instruction
Do not operate Tennelec if P-10 gas pressure supply is less than 200 psig.
Do not use the Tennelec Series 5 XLB counting system to analyze samples with greater
than 50,000 dpm beta/gamma or greater than 6,000 dpm alpha activity as measured with
portable instruments, without concurrence from the CRFLM.
5.1.1 CONFIRM P-10 gas supply pressure is greater than 200 psig.
5.1.1.1 IF pressure is less than 200 psig, CONTACT maintenance for
bottle change out.
5.1.2 ENSURE output regulator is adjusted to 10 ± 1 psig.
5.1.3 IF gas supply was turned off, ALLOW detector to purge for 4 hours.
5.1.4 ENSURE power switch, at rear of sample changer, is in ON position.

5.3 Daily Operational Check
NOTE - Selection of sources in reference to selected counting procedure sequence is
critical to ensure accuracy and valid quality control data.
5.3.1 PRIOR to use, PERFORM (each day) the following checks:
An alpha only and simultaneous background to verify acceptable
background levels. are < 0.5 cpm alpha and < 3.0 cpm beta
Operational checks to verify measured efficiencies fall within + 3
sigma of the fixed mean value established during the calibration. (The
source used to perform the daily source check must be listed by serial
number in the Database Utilities; preferably a source other than the
calibration source should be used.)
The chi-square test is used to test if a sample of data came from a
population with a specific distribution. If the instrument is
functioning properly and correct counting methodology is used, then
expected error can be estimated. Additional error could be the result
of equipment malfunction, improper equipment set-up or operation,
improper source handling or changes in the counting environment
such as background, temperature, power supply, etc.
