Radon-222 measurements at Wairakei, Broadlands and Ngawha
- eds.
The method used for estimation of radon was designed for measuring radon in water, and is modified here to measure radon in steam. At Wairakei, the bores selected were known to emit widely varying chemical compositions. At Broadlands, as many bores as were open were sampled. In addition, analyses were performed on the water of the Waikato River. The material emerging from the bores at Wairakei and Broadlands is a mixture of steam and water, and the water is separated from the steam in a cyclone separator. This water currently flows to waste, and might contain and release radon to the air. It was therefore analyzed. At Ngawha, samples were not collected from the bores which were very few in number, but from the hot springs only. A final sample type was the stack gases at Wairakei. The separated gases from the condensed steam in the power station are mixed with air (about 1:2) and allowed to escape to the atmosphere through four stacks.
