This is number 2 of a 15 part blog series, created by Mr Roy Sefton, Chair of the New Zealand Nuclear Test Veterans Association.

It has long been established that with regard to the British atomic tests in Australia, Britain treated Australia with contempt and with-held vital information. Eventually Australia did wake up and asked the British to leave.

This document to Sir Fredrick Brundett, is signed by the British lead scientist (Sir) William Penny. It relates to radiation samples of two British nuclear detonations in Australia. Penny treats the Australians like fools without the ability to rationalise the most basic scientific information. Penny also suggests deceiving the Australians by giving them a small portion of radiation samples, some days after sampling. Then the radiation levels would have decayed and be lower. Clearly the British did not want the Australians to know the correct levels of radiation that was being generated by the atomic bombs.

You must wonder how much British Operation Grapple mis-information was given to New Zealand Defence and the NZ Government. Such deceit is why NZNTVA cannot trust any Operation Grapple research initiated by the NZ Government. Such research would be based on incomplete information held by the NZ Government and/or supplied by Britain.

The original is difficult to read . It is copied below.

We think that it is likely that the Australians will ask us for filters which have been flown at Mosaic and Buffalo. No doubt they will offer very close security treatment in their Atomic Energy Commission. While I am not very keen on the idea of giving them samples, I do not see how we can refuse. They could, of course, fly planes of their own or they could most easily take contaminated soil particles from the close in area.

They would not know that fall-out contamination from close in areas is very different from samples obtained from the cloud, and only the latter is sufficiently representative to enable quantitative estimates to be made. On the other hand, they are probably very puzzled to know why we fly planes to get samples when it would be very much easier to take a few shovelfuls of dirt from the crater.

On balance I am recommending that if they ask us we give them a little piece of the filters, but that we wait a few days so that some of short-lived key isotopes have decayed a good deal.

Do you wish to consult other people on this question before you give your considered view?

Yours sincerely,

W. G. Penny ENDS<
