General The licensee is required to measure the quantities and concentrations of radioactive material in effluents from his facility to assure that they are within the limits specified in his license and AEC Regulations.
This inspection consisted of a test of the licensee's measurements of radioactivity in actual samples of his ef fluents.
The test consists of comparing the licensee's measurements with those of the AEC's Reference Laboratory. The two laboratories make
.
measurements on the same samples, or on duplicates or splits of the same samples.
The measurements made by the AEC's Reference Laboratory are referenced to the National Bureau of Standards
.
radioactivity measurements system by laboratory intercomparisons.
.
.

Analytical Results This inspection showed all of the licensee's measurements on these samples are acceptable under the test criteria used by the Directorate of Regulatory Operations for comparing measurements reg 3As. (see the, Attachment). The types. of. samples ' tested and

Particulate Filter Analysis Routine.gan;ma spectroscopic analyses of particulate filter samples
. * " ' ?y'
were 'not. performed by'the licensee'at the' time of this comparison.
'
Rather, the laboratory of the Department of Radiological and Occupational Health of the State of Minnesota performed these analyses under a gift agreement between the licensee and the State, Sine July 1,1974, these filters have been returned to the licensee
,
after *he State completes its analysis and the licensee has
.
performed a duplicate analysis.
A verification test of the licensee's own capability in performing this analysis is underway and will be examined in a subsequent inspection.
