In late 1969 and 1970, Drs. Gofman and Tamplin issued a series of technical reports (known as “The G-T Series”) documenting in detail the much larger association of ionizing radiation with cancer-causation than had been previously estimated. These reports examine all the major sources of data from known, human exposures (including certain medical therapies, the Hiroshima-Nagasaki data, the uranium miners, the radium dial-painters) as well as relevant data from animal exposures.

These reports, which are no longer available from the Committee [CNR], were submitted as testimony to two Congressional Committees, and are available at large libraries which keep collections of Congressional Hearings. Three volumes are involved, and the citations given below are correct. It is no error that testimony to one Committee is published in the Hearings of a competing Committee; nor is it an error that the date given to an entire volume may be earlier than the dates on materials included in that volume. Congress can operate that way.
