US study on low-dose ionising radiation
The US Department of Energy (DOE) and National Academy of Sciences have been directed to work together to assess the current status of US and international research on low-dose radiation and to formulate a long-term research agenda under a bill approved by the US House of Representatives.  The Low Dose Radiation Research Act of 2015 directs the two organisations to carry out a research program "to enhance the scientific understanding of and reduce uncertainties associated with the effects of exposure to low dose radiation in order to inform improved risk management methods." The study is to be completed within 18 months.
 
The Act arises from a letter from a group of health physicists who pointed out that the limited understanding of low-dose health risks impairs the nation’s decision-making capabilities, whether in responding to radiological events involving large populations such as the 2011 Fukushima accident or in areas such as the rapid increase in radiation-based medical procedures, the cleanup of radioactive contamination from legacy sites and the expansion of civilian nuclear energy. The aftermath of the Fukushima accident has boosted concern that unduly conservative standards may have large adverse health and welfare costs.

Lowest Australian uranium production for 16 years
Due to the shutdown of ERA’s Ranger plant to June, and despite the rich Four-Mile deposit coming on line, Australia’s uranium production in 2014 at 5897 tonnes U3O8 (5000 tU) was the lowest since 1998. Two thirds of it was from Olympic Dam, where uranium is a by-product of copper.  Production from Four Mile is recovered at the Beverley plant, replacing output from that mine at about double the level.
