to “cook” in an atomic reactor and soak up radioactivity. 33 “We weren’t planning to run a submarine with it,” his father said. “It wasn’t that strong. Still, it doesn’t take so very much radioactivity to make two ounces of an isotope quite powerful—and “You mean he must have been an atomic scientist himself?” Eddie asked. “Let’s just say he—or both of them—have “Be right there,” Eddie said. Then, remembering “Dinner’s ready,” Eddie’s mother called During dinner Eddie wasn’t sure just what he was eating. The idea of spies stealing atomic materials kept building up in his mind. By the asked if he could go over and visit with Teena he and Teena sometimes walked along the Teena answered his knock. Eddie pulled on his trousers and T shirt Eddie apologized, following her inside. looked around for Mr. Ross, but Teena’s over it,” Teena’s mother said. “Oh, yes,” Eddie affirmed. “He was the one who ordered the isotope.” Finished, Eddie went out to breakfast. “What’s an isotope?” Teena asked. him about letting food gather around the “Hi, Mom,” Eddie said. “Gotta hurry. Big radioisotope is, Eddie.” 36 “Well,” Eddie said slowly, “it’s not easy to what it’s all about if you could explain what a metal clamps. It could start cavities. “Aw, Mom—” “Eddie, I asked you to do it three days ago. “I’ve heard of chain reactions,” Mrs. Ross said. to school. I’m expecting to receive shipment of a new radioisotope today.” The very word excited Eddie. In fact, anything having to do with atomic science excited him. He knew something about isotopes—pronounced “Why do they do that?” Teena asked. atomic-science department at Oceanview College without picking up a little knowledge along the way. Eddie knew that a radioisotope was a material which had been “cooked” in an atomic reactor until it was “hot” with radioactivity. out more neutrons. It’s a regular chain reaction.” “Why don’t college professors get summer vacations, too?” Eddie asked. One reason for asking that particular question was to keep from prying deeper into the subject of the radioisotope. Much of his father’s work at Oceanview College was of a secret nature. Eddie had learned not to ask questions about it. His father usually volunteered any information he wanted known, so Eddie stuck to questions which could and would be answered. “Well, with all of the splitting up and moving around of the uranium atoms,” Eddie went them. Remember to switch it off when you’re not actually using it.” “I will,” Eddie promised. He had forgotten several times before, weakening the batteries. 17 It took Eddie over an hour to sort out the asked. “I’ll say they’re dangerous,” Eddie said. newspapers and magazines in the garage, tie “It takes a lot to stop radioactive atomic particles,” Eddie explained. “Especially the gamma rays. They’re the fastest and most dangerous, and the hardest to stop. Alpha and beta “I would,” Eddie said. “Everyone is carefully and doing nothing, there would be an awful lot of energy going to waste. So the atomic scientists take certain elements which aren’t “Oh, guess I’ll stop by and see if Teena soaks up water.” 40 “My, that’s interesting, Eddie,” Mrs. Ross Eddie let Sandy off his chain. The taffy-colored Teena—lived at the far end of the block. Eddie went around to the side door of the “Oh, hi, Eddie,” Teena greeted him, appearing don’t feel, but it destroys your blood cells and tissues, and—well, you’ve had it.” “So that’s what a radioisotope is,” Mrs. Ross up water, it soaks up radiation.” 41 “That’s about it,” Eddie said. “My dad says watch me do a little prospecting with the Geiger counter. But maybe you’re too busy.” That’s how to handle it, Eddie thought. elements. And there are over a hundred elements. Some soak up a lot of radioactivity, and are strong and dangerous. Others absorb only a little and are pretty safe to use. Depends, too, Eddie went inside and followed Teena to “Dad didn’t say exactly,” Eddie answered, Eddie nodded. It was even more serious than its threat of danger to anyone who handled it carelessly. It was a new isotope—a it depended on how they were used. Eddie assumed that anyone who would “She always does, Mrs. Ross,” Eddie said, stoop to stealing isotopes more than likely pretending great injury. “Don’t know why I would be interested in their ability to destroy “So do I,” Teena agreed. Eddie glanced at the kitchen clock. “Oh, since Eddie’s family had moved to Oceanview about this atom business.” 43 “That’s right, Mrs. Ross,” Eddie agreed. “People should talk more and read more about it. After all, this is an atomic age. We might as “Three million billion is a lot of something,” a man’s voice spoke behind him. “What are we talking about, Eddie?” of the dial on the black box wavered slightly. A slow clicking came through the earphones, but Eddie knew these indicated no more than a normal background count. There were slight traces of radioactivity in almost all earth or “Eddie was telling us about atoms,” Teena’s mother said. “Did you know there were three Mrs. Ross a kiss on the cheek. million billion of them in a period?” “How many in a comma?” Mr. Ross said to Eddie, then added quickly, “forget it, Eddie. Teena. Doesn’t seem to be anything out here.” back home.” “All right,” Eddie said. “You know, one of back at Teena’s house. They worked a while on a recent birthday. Then Eddie said good-by “Dinner?” his mother said absently. “It’s not quite four o’clock yet, Eddie. Besides, dinner may be a little late today.” “But this morning you said it would be early,” Eddie reminded her, puzzled. “This morning I didn’t know what might was open. Eddie went through the dining sat stiffly behind his homemade desk, talking rapidly into the telephone. Eddie caught only whether Eddie had discovered any uranium ore that day. Always before, he had shown genuine interest in Eddie’s prospecting trips. “Dad,” Eddie said anxiously, “what—what’s the matter?” wrong, Eddie,” he said, “and I guess there’s no reason why I shouldn’t tell you. It’ll be in the evening papers, anyway.” “Evening papers?” “Eddie, you remember me mentioning this morning about that radioisotope shipment I was expecting today?” disappeared.” “Disappeared?” “The radioisotope was stolen, Eddie,” his father said slowly. “Stolen right out from CHAPTER TWO At the moment, Eddie didn’t pry for further information on the theft of the valuable radioactive isotope. His father had plenty on his however, those two ounces of radioisotope can be very dangerous.” “Fifty pounds,” Eddie said thoughtfully. 32 “I don’t see what anyone would want with a radioisotope,” Eddie said. “Maybe they figured there was something else inside of that lead capsule.”

<question>:
How many times does Eddie go over to Teena’s house? What is the common thread, or reason, for Eddie going over there?

<options>:
A Three times. Each time concern Eddie’s infatuation with Teena, which is why he makes up excuses like going prospecting at Cedar point.
B Twice. Both times concern Eddie’s infatuation with Teena, which is why he makes up excuses like going prospecting for uranium.
C Twice. Both times concern something to do with Eddie’s interest in radioactivity.
D Three times. Each time concern something to do with Eddie’s interest in radioactivity.

<answer>:

C
