Workmen uncover mystery of gamma rays in the park Council workmen discovered a shielded industrial radiography source while clearing a building site in a park in the South of England last December. The source, a sealed gamma-em itting is(> tope, i r i d i u m - 192, was in a closed portable shielded container (Fig. l). Its original activity was 16.6 Ci but has since decayed to 10/JCi. The Department of the Environment told the local paper that the isotope was used for tracing the line of underground
pipes. The site, less than a mile from the NON-DESTRUCTI VE TESTING editorial offices in Guildford, Surrey, UK, was last used to store natural gas pipes in 1969 and 1970. Both t h e police and the Department of the Environment have instigated inquiries into the circumstances of the loss. The workmen from the Guildford leisure and recreation department found the isotope container on the
morning of 16 December last year. The container was still clearly labelled so the workmen recognised it for what it was and the manager called the police. The police notified the physicist at the local hospital, in accordance with the National Arrangements for Incidents Involving Radioactivity (NAIR). He found only the slightest trace of radioactivity and the container was transferred to the Police explosives store in Guildford and later collected by the National Radiological Protection Board (NRPB) at Harwell for disposal. The container of the Gamma Lok type, was manufactured by Tech-Del Ltd. Its maximum capacity is 25 Ci. The isotope was a sealed source of type X44 issued on 29 September 1969 at 16.6 Ci activity. The authorities did not consider the level of radioactivity to be a danger to the public and no public announcement or report was made at the time. The national co-ordinator for NAI R, Dr Ted Wray described the incident for the first time, at a small exhibition laid on to illustrate the work of NAIR when the NRPB building was opened in the summer.
American wins Japanese acclaim Dr Gerold Tenney, a prominent American ndt scientist is now the first non-Japanese member of the Japanese Society for Non-Destructive Inspection. Dr Kanji Imoto, professor of engineering at the Meiji University presented Dr Tenney with a golden pin and scroll to mark the occasion at a ceremony in Japan. The scroll states that it is in appreciation of Dr Tenney's great contributions to research in ndt and to the improvement and spread of new techniques over the years and that his senlices are 'especially distinguished'.

The Department of Industry had to agree to the new articles so the amalgamation was protracted. The vice president of the NDT Society, Mr Dennis Wells, chaired the July meeting in place of Mr Ken Williams, the president who was unwell.
Big vote for British ndt unity A meeting in London in July took the final decision to amalgamate the two British societies into the new British Institute of Non-Destructive Testing. The poorly attended extraordinary general meeting of the British NDT Society was evenly split on the merger but the 16 votes cast there were swamped by a 90% amalgamation vote from society members throughout the country. The other society, the Society of Non-Destructive Examination, just reached the necessary 75% of votes cast in a postal ballot counted the week before. The British Institute of Non-Destructive Testing should start life next January with a membership of about 1700 including the 100 members of SONDE. Over two thirds of SONDE members voted contrasting with the one third poll of the NDT Society of Great Britain. The vote is the last move in the latest attempt to amalgamate the societies. SONDE is a small unincorporated body which has now agreed to dissolve itself into the new incorporated institute which is legally a continuation of the British NDT Society, which in effect has only changed its name and articles of
