 Who is Teena and what role does she play in Chapter one and chapter two?
YOUNG READERS Atom Mystery 11 CHAPTER ONE It was only a dream. Still, one clue is as good as another when it comes to hunting uranium ore, I guess. It could start cavities. In fact, anything having to do with atomic science excited him. You couldn’t have a father who was head of the atomic-science department at Oceanview College without picking up a little knowledge along the way. When carefully controlled, the radiation stored up in such isotopes was used in many beneficial ways. One reason for asking that particular question was to keep from prying deeper into the subject of the radioisotope. His father usually volunteered any information he wanted known, so Eddie stuck to questions which could and would be answered. It took Eddie over an hour to sort out the newspapers and magazines in the garage, tie them in neat bundles, and place them out on the front curb for the Goodwill pickup. The best way to get there was by rowboat across Moon Bay, and that was too long a row to be starting now. Besides, there were plenty of other places around the outskirts of Oceanview where likely looking rock formations invited search with a Geiger counter. 19 Christina Ross—whom everybody called Teena—lived at the far end of the block. 20 Eddie went inside and followed Teena to the kitchen. They had been ever since Eddie’s family had moved to Oceanview and his father had become head of the college’s atomic-science department. Teena’s father was chief engineer for the Acme Aviation Company, one of the coast town’s largest manufacturing concerns. 22 “Oh, yes, it’s fun, Mother,” Teena replied, wrapping wax paper around a sandwich. A slow clicking came through the earphones, but Eddie knew these indicated no more than a normal background count. It was in the air itself, caused by mysterious and ever-present cosmic rays, so there was always a mild background count when the Geiger counter was turned on; but to mean anything, the needle had to jump far ahead on the gauge, and the clicking through the earphones had to speed up until it sounded almost like bacon frying in a hot skillet. After they had hiked and searched most of the forenoon, Eddie said, “We might as well call it a day, Teena. Then he told Teena about his dream. It was midafternoon by the time they arrived back at Teena’s house. They worked a while on a new jigsaw puzzle Teena had received on a recent birthday.
 Teena is Eddie’s friend and neighbor. She accompanies him on a prospecting hike, where they don’t find any trace of radioactivity but still enjoy a lunch together.
