Ni-63 is of considerable interest and importance in radionuclidic metrology as well as for radiation protection surveillance around nuclear facilities. Paper: “The Astonishing 63Ni Radioactivity Reduction in Radioactive Wastes by Means of Ultrasounds Application” (Rosada, Cardone and Avino) Posted on January 2, 2020 • 25 Comments Thanks to Curbina for mentioning in a different thread this paper, published on ResearchGate in November 2019, which I had not seen before. Abstract Beta particles emitted from 63 Ni were used to bombard in vacuum a steel target covered with a film of aluminum. It was found that the ratio of intensities of the characteristic X-rays generated in this way both in the film and in the substrate can be used to determine the thickness of the aluminum film.

Based on the the results from this project in 2014-2015, When results are compared with 63Ni activation predicted by neutron doses for Hiroshima survivors, good agreement is observed at the distances most relevant to survivor data. These findings provide, for the first time, clear measurement validation of the neutron doses to survivors in Hiroshima. Abstract The product of the grain boundary diffusion coefficient and width, D′δ, has been measured directly for the diffusion of 63Ni along grain boundaries in high-purity NiO. These measurements have been made at an oxygen pressure of 1 atm in the temperature range 500–800°C, and also at an oxygen pressure of 7 × 10−6 atm at 700°C.
