Alpha radiation can't penetrate the skin, but it can be inhaled, swallowed, or can enter through a cut. This ''spent fuel pool'' type of storage is designed to be a temporary safety measure. radiation? A suitable table of results might look like this: According to the inverse square law, the intensity, Intensity is proportional to the corrected count rate, C, so, Comparing this to the equation of a straight line, y = mx, Square each of the distances and subtract the background radiation from each count rate reading, Plot a graph of the corrected count rate per minute against 1/, If it is a straight line graph through the origin, this shows they are directly proportional, and the inverse square relationship is confirmed, The Geiger counter may suffer from an issue called dead time, This is when multiple counts happen simultaneously within ~100 s and the counter only registers one, This is a more common problem in older detectors, so using a more modern Geiger counter should reduce this problem, The source may not be a pure gamma emitter, To prevent any alpha or beta radiation being measured, the Geiger-Muller tube should be shielded with a sheet of 23 mm aluminium, Measure the count over the longest time span possible, A larger count helps reduce the statistical percentage uncertainty inherent in smaller readings, This is because the percentage error is proportional to the inverse-square root of the count, Reduce the exposure time by keeping it in a lead-lined box when not in use, Do not point the source at anyone and keep a large distance (as activity reduces by an inverse square law), Safety clothing such as a lab coat, gloves and goggles must be worn.
