Inter-Laboratory Cross-Check
Program or Performance Test Program
One of the quality control aspects of an effective
quality-assurance and quality control program of a radiochemical
analysis laboratory is participation through an inter-laboratory
blind QC cross-check program. It is recommended by the United States
Nuclear Regulatory Commission, the Institute of Nuclear Power
Operations and ANSI N42.23 -1996 “American National Standard
Measurement and Associated Instrument Quality Assurance for
Radio-assay Laboratories” as part of a standard quality control
activity.
NTS offers Inter-laboratory Quality Control Cross-Check blind
samples at environmental levels in water, milk, soil, simulated
vegetation, air filters and charcoal cartridges. NTS also provides
blind simulated routine effluent samples for the laboratories that
provide analytical services support for Nuclear Power Plant
Radiological Effluent monitoring Program (REMP) and samples for
10CFR61 specified program. The program provides quarterly, blind
samples at concentrations that would permit an evaluation of your
analytical accuracy. The types of sample matrix and radionuclide
provided depends on the customers specifications.
Reporting Procedures
Sample price included comparison report with one result per
sample. Reports for multiple results (e.g., detectors,
shelves, etc.) are available at an additional cost. For
nuclear power plant related monitoring programs, the customer
specifically will receive a report using the NRC Confirmatory
Measurements criteria and format for comparing analytical
measurement results. The report is issued within 15 work days
from receipt of sample analysis results reported by the
customer. The known values along with client values are
tabulated with the ratios of the known-to-reported values.
