How is radiation used to control the thickness of sheets of plastics, paper, and metals? A. Random atoms of the bulk material are irradiated. When the sheets are made they are checked to see if the irradiated atoms are evenly distributed throughout the sheet, indicating the sheet is in the correct proportions.

B. The radiation is passed through the sheets. If they are too thick or thin the amount of radiation that passes through changes and a signal is sent to the sheet rollers.

C. The raw block of material is sliced with a precise beam of radiation only a few atoms thick that ensures each sheet is the exact same size.

D. The surface of the raw materials are covered in radiation. When they are passed through the rollers they are shaved down until no more radiation is detected coming off them.
