Reduction in Radiation Exposure with Distance from Source

Not what you're looking for?

Ask Custom Question

An alternative to shielding of a radiation source is to extend the distance between the radiation source and the worker. The initial design places the worker 1m, from the source. If the design was revised so the worker was 10m from the source, what percentage reduction in radiation exposure would there be for the second position relative to the first?

Solution Summary

We calculate the amount of reduction in radiation exposure when the distance from the source is increased from 1 to 10 meters.

    So in part A you are asked to find the exposure if the point source is moved from d = 30 cm to d = 5 cm. Since we are at a closer distance one would expect that the intensity of radiation received will be greater.

    Protection from radiation for public health purposes requires handing out the best possible information so people can manage exposure and ensure that time; distance and shielding are in place to reduce exposure damage.

  • Protection from Radiation

    (a) The radiation counts from a source are inversely proportional to the square of the radius (i.e. distance) from the source. So the radiation counts 3 feet away from a source will be 3^2 = 9 times lower than from 1 foot away.
