CASTLEFORD head coach Daryl Powell has amassed a deep squad in order to combat a Super League season unlike any other. A late start to the season, prompted by the coronavirus pandemic, means teams will face the extra demands of three sets of midweek fixtures as organisers cram 25 rounds into the regular season, as well as the Challenge Cup, from March 26 to September 28. With the exception of newly promoted Leigh, who are expected to add to their roster before the big kick-off later this month, Super League clubs have already handed out 30 or more squad numbers as coaches prepare to rest and rotate. ....
Scientists develop method to detect radioactive materials in gold, copper Collision cell. (Image by Andrea Starr, courtesy of the Pacific Northwest National Laboratory). Researchers at the US Department of Energy’s Pacific Northwest National Laboratory have developed a method that holds promise for transforming how ultra-trace elements are separated and detected. Ultra-trace levels of radioactive materials can wreak havoc on sensitive equipment such as microchips, transistors, sensitive sensors, or instruments searching for evidence of currently undetected particles believed to comprise most of the universe. Sign Up for the Suppliers Digest Sign Up In a paper published in the Journal of Analytical Atomic Spectroscopy, the scientists said that low levels of troublesome naturally occurring radioactive elements like uranium and thorium atoms are often tucked among valuable metals like the gold and copper that go into the electrical components of ....

In most cases, low levels of radiation are not a health concern. But some scientists and engineers are concerned about even trace levels of radiation, which can wreak havoc on sensitive equipment. The semiconductor industry, for instance, spends billions each year to source and scrub ultra-trace levels of radioactive materials from microchips, transistors and sensitive sensors. ....
