On 26 April 1986, one of the worst nuclear disasters in history occurred at the Chernobyl Nuclear Power Plant. Less than three weeks later, Voice was one of 14 British nuclear scientists and engineers, several of them members of the Pro-Nuclear Group at Caithness, who volunteered to help with the decontamination of the area around Chernobyl. He visited Russia several times subsequently. In 1991, following a return to Chernobyl he said in a public lecture that his findings bore out those of the recent UN-sponsored report, and that he could find no evidence of increased childhood leukemia, and that some wildlife species had multiplied many-fold. He deplored the gross exaggeration and misreporting of the aftermath as media hype. Later, following a two-week visit to Dubna, the home of JINR, Voice appealed to people in his part of the world to become pen-pals with Russians, who are “thirsting for information about life in the West”.
