Bomb Test Fall-out
The director of the National Laboratory (Mr G. E. Roth) said yesterday that a statement about French bomb test fall-out in New Zealand, attributed to him and printed in “The Press” last Saturday, contained a number of errors. “The first series of French tests in the Pacific did not end on July 3, 1970, but on October 5, 1966,” said Mr Roth. “Furthermore, I neither mentioned ‘conventional thermo-nuclear explosions’ nor a ‘thermo-nuclear trigger,’ since either of these is a contradiction in terms. "Thermo-nuclear’ means the reaction used in the hydrogen bomb itself, while the ‘trigger’ uses a fission reaction, commonly called a ‘conventional atomic bomb.’ “I explained that the radioactive debris from the Trigger’ provides the first indications of the arrival of fresh fall-out from a French thermo-nuclear bomb test because, after its journey round the Southern Hemisphere, the measurable debris consists predominantly of debris from the ‘trigger’ used.”
