Abstract : The effects of cyclotron irradiation upon the hardness, the stress strain relationship, and the electrical resistance of thorium 347, stainless steel, and zirconium have been determined. The irradiations were carried out below 100 deg C on the 60 inch Crocker cyclotron. The electrical resistance measurements were made at -146 deg C and other measurements were made at room temperature. The results indicate that the changes in the properties due to irradiation tend to increase in magnitude up to a saturation point. The change in the thermal conductivity due to the damage has also been estimated by calculation. No changes in the metallurgical structure were noticed.
