Professor Emeritus of Physics at the University of Pittsburgh. Professor Cohen was a staunch opponent of the so-called Linear no-threshold model (LNT) which postulates there exists no safe threshold for radiation exposure: We conclude that all the world's energy requirements for the remaining existence of life on Earth could be provided by breeder reactors without the cost of electricity rising by as much as 1% due to fuel costs. This is consistent with the definition of a "renewable" energy source.

Professor Emeritus of Physics at the University of Pittsburgh: Plutonium is constantly referred to by the news media as "the most toxic substance known to man." Ralph Nader has said that a pound of plutonium could cause 8 billion cancers, and former Senator Ribicoff has said that a single particle of plutonium inhaled into the lung can cause cancer. There is no scientific basis for any of these statements, as I have shown in a paper in the refereed scientific journal Health Physics (Vol. 32, pp. 359-379, 1977). In spite of the facts we have cited here, facts well known in the scientific community, the myth of Pu toxicity lingers on. The news media ignore us, and prefer to continue scaring the public at every opportunity.

D. Lightfoot, W. Manheimer, D. Meneley, D. Pendergast, G. Stanford: Nuclear fission energy is as inexhaustible as those energies usually termed "renewable", such as hydro, wind, solar and biomass. But unlike the sum of these energies, nuclear fission energy has sufficient capacity to replace fossil fuels as they become scarce. Uranium could power the world as far into the future as we are today from the dawn of civilization - more than 10,000 years ago. Fast reactors have distinct advantages in siting of plants, product transport and management of waste.
