Dr Lowenthal was the leader of a small Group at the AAEC which established the Australian Standards of Radioactivity. He was invited in the mid-1970s to represent Australia on the Consultative Committee for Standards for the Measurement of Ionising Radiations of the International Committee for Weights and Measures, Paris. He has published some 15 research papers with other members of his Group in refereed scientific journals. He was for six years honorary Australasian Editor of the International Journal of Applied Radiation and Isotopes. He is currently an honorary consultant for Nuclear Medicine and is also a Visiting Fellow within the School of Mechanical Engineering at the University of New South Wales. For his contributions to radionuclide metrology he was named Chevalier de l'Ordre National du Mérite by the President of France in 1994 and was named by the Governor-General, a Member of the General Division of the Order of Australia in 1999.

Klappentext

This book shows how to use radioisotopes and the emitted ionizing radiations effectively and safely. It describes decay and stability criteria, necessary precautions to ensure radiation protection and the detection of alpha, beta and gamma rays including spectrometry. Chapters cover calorimetry, liquid scintillation counting, how to use secondary standard instruments, high resolution detectors and how to calculate counting results estimating uncertainties and allowing for the statistics of radionuclide decays. Other subjects examined include industrial and scientific applications of alpha, beta, and gamma rays, neutrons and high energy radiations.

Zusammenfassung
This concisely written book introduces radioisotopes, ionising radiations and their numerous applications. Explanation is provided by selected examples, including methods for the accurate monitoring of sealed and complex systems. The book is particularly useful to engineers, scientists, teachers and students who work with nuclear radiations.
