Dear Participant,

   Enclosed are the results of the Nuclear Radiation Assessment Division (EMSL-LV)
Performance Evaluation Study for Blind-A; October 19, 1993.

   The known value for each analysis was determined by gravimetric methods,
checked by chemical analyses performed by EMSL-LV's Radiochemistry Laboratory,
and compared to the participating laboratories' grand average.

   The expected precision, determined by the known value, was taken from
'Table 3. Laboratory Precision:  One Standard Deviation Values and Control Limits
for Various Analyses", which is based on data accumulated over the years by the
Performance Evaluation Program, and can be found in the Environmental Radioactivity
Performance Evaluation Studies Program and Radioactive Standards Distribution
Program information brochure.

   Please take a few minutes to review this report and the analytical data your
laboratory submitted to us.  If there are any apparent discrepancies, please notify us
immediately.

   We encourage you to make use of the computer-automated data-entry system
that has been in place for some time now.  As the number of participants increases,
and it becomes unrealistic for us to receive results by mail or FAX, the computer
system will be our only avenue for accepting data.

   If you have any questions or comments, please send a message via the data-entry
system or contact George Dilbeck at 702/798-2104 or Patricia Honsa at 702/798-2141.
                                          Sincerely,
                                          George Dilbeck

   The following pages consist of separate sections for each of the nuclides in this study with four
parts per section.  After the first, each part is separated from the next by a new page or a thick
horizontal bar.  The first page of each section is a statistical summary for the nuclide and starts
with a statement of the known value, the control limits, and the warning limits.

   The warning limits are placed at two normalized standard deviations above and below the
known value and the control limits are three normalized standard deviations above and below
the known value.  If you keep control charts, these values will be useful for anticipating problems
with the accuracy of your analytical methods.

   The coin shaped pie chart at the top of the summary page shows the fate of all the samples
sent out in number andฐpercentage terms. The pie chart starts at the top and rotates clockwise.
The first sector represents those participants who submitted analytical results within both the
warning and control limits. The next sector represents those who are in the warning region but
not out of control. The third sector represents those who are out of control, but have passed
the outlier test. The fourth sector represents those who have failed the outlier test. The last
sector represents those participants who have failed to respond properly. This is the case if no
analytical results were returned, or less than three determinations were reported, or if the results
were received too late. The reeding on the edge of the coin is spaced at one percent intervals, and
the sector shading becomes darker as the data reliability decreases. Sectors with zero width are
not shown.
   The table in the center shows a number of statistical quantities calculated from the submitted
data based on the mean and median values in relation to the known value, both before and after
outlier removal. The lower pie chart uses the same construction as the upper chart and shows
the distribution of properly submitted data in terms of deviation from the known value divided
into sectors representing  one, two, three, and greater than three normalized standard deviations.

   The second part is an  alphabetical listing, in lab-code order, of submitted data and several
calculated quantities. An entry that is shaded has been rejected because of one of the reasons
listed above or failure of the  outlier test. The fifth and sixth columns are a measure of laboratory
precision. The Range analysis is a normalized value that you may use to keep precision control
charts. If this value is between 2.0 and 3.0, your analytical process precision is in the warning
zone; if it exceeds 3.0 it is out of control. The eighth and ninth columns are the differences from
the mean of all non-outliers and from the known value, respectively. A tag symbol may appear in
the last column. Each page with tags has a symbol definition summary at the bottom.  If there is
no tag symbol, the data is within the control limits, but it may be in the warning zone.

   The third part is a three-column listing of result average, tag symbol, and lab-code in average
order excluding those labs not responding properly. In this order, all outliers and out-of-control
results appear at the top  or bottom of the  list.
   The last part is two bar chart displays showing frequency distributions of responding
participants. The first chart places the known value at the center and a bar at each 0.2 unit of
expected precision.  The second chart places the mean of the reported measurements at the center
and a bar at each 0.2 unit of standard deviation. In both cases,  a bar includes those results within
0.1 unit up to the maximum of six. Any results more than six units from the center value are
shown cumulatively by a  shaded bar one past the sixth unit. If the central tendency of the known
value distribution falls away from the center, an error in accuracy is indicated. If the  distribution
is broad, poor precision is indicated. The mean value distribution is similar but uses the average
and standard deviation of reported results as its basis.

     The Range Analysis(R + SR) is calculated from the range, mean range and standard error of
  the range values.  The range is the difference between the maximum and minimum results for the
  laboratory. The mean range is calculated by multiplying the expected precision by 1.693(for three
  results).  The standard error of the range is calculated by multiplying the mean range by 2.575(for
  three results), subtracting the mean range from this product, and dividing the result by 3. If the
  range is greater than the mean range, then the range analysis is calculated by subtracting the
  mean range from the range, dividing the result by the standard error of the range and adding 1.
  If the mean range is greater than or equal to the range, then the range analysis is calculated by
  dividing the range by the mean range.

     The normalized deviation of the mean from the grand average is calculated from the deviation
  of the mean from the grand average and the standard error of the mean values.  The deviation of
  the mean from the grand average is calculated by subtracting the grand average from the
  average of the laboratory's three results. The standard error of the mean is calculated by
  dividing the expected precision by the square root of 3(the number of results). The normalized
  deviation of the mean from the grand average is calculated by dividing the deviation of the mean
  from the grand average by the standard error of the mean.

     The normalized deviation of the mean from the known value is calculated from the deviation of
  the mean from the known value and the standard error of the mean values.  The deviation of the
  mean from the known value is calculated by subtracting the known value from the average of the
  laboratory's three results.  The standard error of the mean is calculated by dividing the expected
  precision by the square root of 3(the number of results). The normalized deviation of the mean
  from the known value is calculated by dividing the deviation of the mean from the known value by
  the standard error of the mean.

     A complete explanation of the statistical calculations involved in the report may be found in
  the Environmental Radioactivity Performance Evaluation Studies Program information brochure
  [Draft Revision of EPA-600/4-81-004], available from George Dilbeck, EMSL-LV, 702/798-2104.
