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.

An empty planchet

END plate.

5.2.4 LOG count into SAIMS Quality Control Log using next sequential number

AND

QC is Quality Control designator

YY is last two digits of year

XXXXX is sequential sample number for year.

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.
