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?
1) An X-ray film, because it can detect the low frequency X-rays.
2) An X-ray film, because it can detect the low energy infrared radiation.
3) A Geiger counter, because it can detect the high energy gamma rays.
4) A Geiger counter, because it can detect the highly penetrating ultraviolet radiation.
