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

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
