[Nuclear waste history](5)

รูปภาพ
Nuclear waste history(5) Some radioactive elements like tritium and krypton-85 are very difficult and very expensive to trap. But the La Hague plant is permitted to discharge most if not all into the environment. Permission was granted by the Nuclear Safety Authority which oversees all installations. Its CEO is Andre-Claude Lacoste. Q: How are the discharges from La Hague site determined? A: It is a process in which the operator, in this case Areva, now writes us to explain what waste they would like to do. First we do a technical study using our technical back-up, the Nuclear Security Protection Institute (IRSN),  to verify if the request is technically reasonable or if the request corresponds to reasonable norms. A second study determines if the waste such as requested will have an impact on the populations of the area. We then try to set a waste authorisation level as low as possible , taking the 2 element into account. Q: When processing spent fuel, rare gases are released,...

Sitting outweighs exercise

รูปภาพ
People who exercise regularly may still be at risk for heart disease and diabetes if they spend the rest of their day sitting behind a desk or sprawled on the sofa. Indeed, an American Heart Association (AHA) study found U.S. adults are sedentary for up to eight hours each day. It doesn’t help matters that fewer than 20 percent of jobs require employees to be active—down from 50 percent in the 1960s, NBCNews.com reports. No amount of exercise can offset the harmful effects that prolonged sitting can have on the heart and blood vessels, the AHA cautions. People should avoid sitting for too long—even if they meet current physical activity recommendations and get at least 150 minutes of moderate exercise each week, the group advises. “Given the current state of the science on sedentary behavior,” says AHA’s Deborah Rohm Young, “it is appropriate to promote the advisory ‘Sit less, move more.’” Best Roach Killer 2020 Best Wood Glue Best Power Inverter Best Electric...

Bookworms live longer

Bibliophilia is good for your health: A new study suggests that people who read books regularly may add nearly two years to their lives. Researchers at Yale University examined the reading habits of 3,635 people over 50 and found that the ones who buried their noses in a book for more than 3.5 hours each week—or 30 minutes a day—were 23 percent less likely to die over the course of the 12-year study, reports The Christian Science Monitor. Even after variables such as health, education, and income were taken into account, bookworms were 17 percent less likely to die over the same period than their non-reading peers. It’s unclear why reading is associated with this “survival advantage,” but the researchers suggest delving into novels promotes cognitive processes, such as empathy and emotional intelligence, which can boost longevity. Unfortunately, reading magazines and newspapers may not provide the same benefit. “We uncovered that this effect is likely because books engage the reader’s ...
