However, the radioactive wastes generated after nuclear fission takes place are the principal environmental concern. They must be well disposed of in specially designed pools and then maintained in costly dry storage containers. They are highly radioactive, hazardous to humans even with short-term exposure. The disposal and storage of these radioactive isotopes as well as the decommissioned reactors cost taxpayers more than tens of millions of dollars annually. le; the White sed Scientists are dedicated to the reuse of nuclear wastes. The researchers at the University of Bristol in the U.K. are trying to encapsulate nuclear waste within diamonds. “The radiation is locked safely away inside the gemstone, meanwhile providing a clean energy supply like a long-lasting battery,” said the head of the team. They aim at carbon-14, a radioactive isotope with a half-life of around 5,730 years and available in graphite blocks used to cool the uranium rods. By heating the blocks, scientists convert carbon-14 into a gas and then gather it to form a kind of “diamond”- since diamonds are just another form of carbon. To safely block the short-range radiation it emits, scientists suggest the most solid substance on Earth, diamond, to contain it. A diamond beta-battery comes into being as a result. carly The same as what is confronting in dealing with nuclear waste stockpiles, the diamond battery is highly-priced, too expensive to manufacture. However, researchers are still holding an optimistic attitude toward it, speculating about its possible applications in anything where

Therefore, it is important to take a look at the causes of poor sleep and try to fix them. Various factors can keep us awake at night. 32. Our body has a built-in clock that controls our sleep schedule. The blue light from electronic screens pushes that clock back, making it hard for our body to relax. In fact, blue light shifts our natural clock twice as much as any other type of light. As a result, you do not feel sleepy until much later or at all. Another factor in staying up late into the night is the food you have eaten before you go to bed. 33. Such discomfort can make the body restless during the night. Additionally, specific spicy foods, such as chilies, raise your body temperature and make sleeping difficult. To improve the quality of your sleep, try following these tips. 34.

the SW eft da al V. 閱讀測驗:9% It was time for another women's five-thousand-meter qualifying heat*. A group of seventeen female Dis runners from different countries lined up for the start of the race. The crowd in Rio's Olympic stadium cheered loudly when the starting gun went off. Charging ahead, the athletes strove for position and to stay AD at the front of the pack. Bunched tightly together, the group circled the track several times. Then, with less than half of the race to go, drama struck. New Zealand's Nikki Hamblin tripped on the heels of the Japanese runner in front of her. She crashed to the ground, unfortunately taking the American athlete, Abbey D'Agostino, down with her. The latter was the first to get up. Instead of continuing the race, D'Agostino quickly turned around to help Hamblin to her feet. She didn't even realize how seriously she had been injured since she was too concerned about the other runner. She was hardly able to stand due to the pain and fell to the ground again. Now it was Hamblin's turn to help D'Agostino up. With the crowd's encouragement, the two were able to carry on with the race despite their terrible falls. Hamblin and D'Agostino even managed to complete the event although they were far behind the eventual medal winners. Apart from receiving the 2016 Olympics Fair Play award for competing with such good spirit, both runners were also given the opportunity to run again in the five-thousand-meter finals. After all, it's not always about winning. 註:qualifying heat 資格賽 ) 31. Which of the following is NOT true about the incident? (A) It occurred in the 2016 Rio Olympics.
