[O06-P08] Elements which keep coming cosmic rays from passing
Keywords:cosmic rays, cutoff ratio, obstacle
Focusing on the property of cosmic rays to be blocked, we conducted an experiment using a variety of materials to determine how much cosmic rays are blocked by each material.
The three substances used in the experiment were soil, sand, and paper. The values representing the properties of the substances were linked to the substances, and the correlation between the blocking rate and the substances was investigated. The quantities that represent the properties of the substances here are the filling rate and volume. The filling rate was calculated from the volume measured by placing the substance in water and the apparent volume with gaps.
The experimental method was set up so that the cosmic watch was under the container containing the substance. cosmic watch is the name of a machine that measures the strength and number of cosmic rays coming from space. In this experiment, the containers used for the experiment and the location of the experiment were unified. In addition, two cosmic watches were used at the same time to prevent differences in the measurement date and time from affecting the results.
The results showed that the interception rate was higher for paper, soil, and sand, in that order. It was also found that the number of cosmic rays observed increased when sand was used for interception, compared to the case where there was no sand interception. In addition, when we look at the filling ratio, the filling ratio is in the order of paper, sand, and soil, so we can say that there is a relationship between the blocking ratio and the filling ratio when we look at the difference in the blocking ratio between paper and sand, and between paper and soil. However, when looking at soil and sand, no such relationship was observed.
The first consideration is that sand may be radiating something that could affect the cosmic ray measurements. The second consideration is that each material has a certain intensity of cosmic rays that are easy to block, and that varies from material to material.
As a way to verify this, we plan to analyze the blocking ratio for each intensity of cosmic rays. In this study, we will use water for the experiment instead of paper, which was prone to handling and accuracy problems in this experiment.
