The first-ever discovery of an extraterrestrial radioactive isotope on Earth has scientists rethinking the origins of the elements on our planet. The tiny traces of plutonium-244 (Pu-244) were found in ocean crust alongside radioactive iron-60. The two isotopes are evidence of violent cosmic events in the vicinity of Earth millions of years ago.
Star explosions, or supernovae create many of the heavy elements in the periodic table, including those vital for human life, such as iron, potassium and iodine. To form even heavier elements, such as gold, uranium and plutonium it was thought that a more violent event may be needed, such as two neutron stars merging.
Abstract
A feasibility study is presented on a newly developed microdosimetry system named Octobox, for its application in low dose rate, mixed radiation environments. A full characterization of the device was performed at the Heavy Ion Medical Accelerator in Chiba (HIMAC), Japan, out-of-field of various heavy ion radiation fields 290 MeV/u C, 230 MeV/u and 490 MeV/u Si and 400 MeV/u Ne ions, as well as a low dose rate Rn environment at the Australian Nuclear Sciences and Technology Organization (ANSTO). The device was shown to collect adequate statistics in a short period of time when compared to the MicroPlus probe with a single microdosimeter, while accurately measuring microdosimetric quantities and the corresponding average quality factor (Q¯) and dose equivalent (H) of the mixed radiation field. Good agreement of the microdosimetric spectra was also shown with Geant4 simulations for all presented ion fields. Based on the findings in this study, the Octobox is capable of
IMC” or the “
Company”) is pleased to announce the formation of the IMC Technical Advisory Board and associated initial appointments. The Technical Advisory Board is comprised of internationally recognized industry experts and thought leaders, with significant scientific, technical, and market expertise relating to rare-earth elements (“
REEs”) and other critical materials.
The Technical Advisory Board will advise and support IMC’s leadership team in making important technical and logistical decisions, as the Company continues to advance the commercialization of IMC’s proprietary RapidSX™ technology, for the economic, commercial-scale separation of both light REEs (“
LREEs”) and heavy REEs (“

Prevent Poaching of Rhinos: A global collaborative and innovative project using nuclear science to prevent/reduce rhinoceros poaching has been launched recently in which Russia s integrated nuclear power player Rosatom a key partner. Australian Nuclear Science and Technology Organization (ANSTO) is also a partner.
According to Russia s integrated nuclear power company Rosatom, the anti-poaching Rhisotope Project was initiated by the University of Witwatersrand (WIT) and is being implemented under a global collaboration with Australian Nuclear Science and Technology Organization (ANSTO), Colorado State University (USA), Rosatom (Russian Federation) and the Nuclear Energy Corporation of South Afric
