As a result of the excellent work done in this area by the Idaho Laboratory during the past eight years, the laboratory has gained a reputation among the milling industry, the Statas, the Public Health Service and the FNPCA for performing high caliber work and producing reliable results. Thus, their results are accepted with-out question by these groups.
The Idaho Laboratory is located near the milling area thereby facilitating communication with those concerned with the nilling industry, particularly the Agreement States which will probably have need to consult with them on analytical matters.
Scme suggestion appears to have been made that the New Brunswick Laboratory should perform all analytical work for the Regulatory Program. So far as I have been able to find out, the New Brunswick Laboratory is highly competent in the area of uranium ore analysis, and analysis of other materials in the uranium mining and milling feed material area.

Division of Materials Licensin w ANALYTICAL CHDlILAL SUPPORT OF 'IllE REGULATORY PROGRAM I
c.cf 1 I have read Mr. r!. L. Ginkel's memorandum to you of November 8,1966, JT dealing with the capabilities of the NRTS-ID Analytical Laboratory to support the Regulatory Program.
I can support the representations Mr. Ginkel makes, both through direct knowledge of Claude Sill, his staff and his capabilities, as well as by reason of the work the laboratory has done in the past for the Regulatory Program.
Since 1959 the Idaho !!calth and Safety Laboratory has provided to the Regulatory Staff analytical support for the uranium milling program.
This support has included the development of both new and improved methods of analysis for the various radionuclides involved in uranium nilling as well as the performance of routine sample analysis (e.g.,
air, water, tailings, bioassay, etc.).
Improvements have been made by the Idaho Laboratory in both the sentivity and reliability of the analytical methods. As a result of the excellent work done in this area by the Idaho Laboratory during the past eight years, the laboratory has Sained a reputation among the milling industry, the States, the Public Health Service and the FWPCA for performing high caliber work and producing reliable results. Thus, their results are accepted with-out question by these groups.
The Idaho Laboratory is located near the milling area thereby facilitating communication with tho::e concerned with the milling industry, particularly the Agreement States which will probably have need to consult with them on analytical matters.
Some suggestion appears to have been made that the New Brunswick Laboratory j
should perform all analytical work for the Regulatory Program.
