suspicious dosimeter radioactivity "This seems suspicious. Who would come out here to give us a gift and run away?" "Well, the card says Santa Claus." But you're not convinced. You take the gift into the research lab. Sam helps you take an X-ray, but the X-ray machine can't see inside. Then you notice a warning light on the dosimeter. "Radioactivity," Sam warns. You throw the present into a lead box. You are shocked. "Somebody tried to kill us. We have to do something." Sam tries the radio. "It's not working." What will you do? I will go outside and look around. I will go get help.
