A laboratory is suspected to be contaminated with radiation from a radioactive material. Which of the following detection instruments can be best used to detect this radiation?
O An X-ray film, because it can detect the low frequency X-rays
O An X-ray film, because it can detect the low energy infrared radiation.
OA Geiger counter, because it can detect the high energy gamma rays
OA Geiger counter, because it can detect the highly penetrating ultraviolet radiation.
