This is in further response to your invitation of March 24, 1960, to the Director, Bureau of Mines, to provide a brief statement for the public hearings to be held by the Special Radiation Subcommittee of the Joint Committee on Atomic Energy on the subject, "Radiation Protection Criteria and Standards: Their Basis and Use."

In a letter of April 8, 1960, to you, it was stated that the Department
of the Interior would bring up to date the information provided for the
bearings on Federal-State Relationships. After a review of what is
requested and the material provided for the earlier hearings, the
Department finds that with a minor addition the statement of September 11,
1958, to Senator Clinton P. Anderson defines the present situation.
That statement, with its enclosures, and the supplemental material are
submitted.

Sincerely yours,

hape a Harl.
