Australian emergency services has located the lost sealed source, the BBC reported early February 1.
The caesium-137 capsule, part of a density gauge used at Rio Tinto’s Gudai-Darri mine in Western Australia, was found after a survey vehicle travelling at 70 km/h (43 mph) detected radiation, according to the report. According to Australia’s Department of Fire and Emergency Services, the capsule was located on the roadside of the Great Northern Highway, south of Newman. A serial number verified it was the lost source.
Last week, as reported yesterday by Nuclear Newswire, Australian authorities began searching 1,400 kilometers (870 miles) of Australia’s Great Northern Highway, between Perth and the remote town of Newman, for a lost sealed-source capsule containing cesium-137. The source was part of a density gauge used by mining company Rio Tinto at its mining operations in Western Australia.

This textbook presents students with nuclear concepts, models, vocabulary, and problem-solving skills that are essential for success in subsequent course work in reactor theory and engineering. Designed for a sophomore science or engineering student with a firm foundation in the basics of college physics and mathematics through ordinary differential equations, Mayo's book addresses concepts in modern physics (special relativity, quantum concepts, etc.) and develops those concepts as necessary in the presentation of the text material. The text objective is to present fundamental nuclear principles in a clear and understandable yet physically sound manner.
