Concept explainers

Radiation

Radiation can be described as the energy in the form of a particular matter or electromagnetic waves traveling in the air and can be in the form of light, sound, and heat. Radiation can be detected through special instruments like X-rays. The radiation from a cooler object is less intense as compared to the radiation from hot objects.

The amount of radiation received per unit time by a person working near a radioactive source, commonly called the dose rate, is measured in rem hr-1. The safety regulations forbid dose rates in excess of 7.5 × 10-4 rem hr-1. The γ dose rate from the 4219K source is found to be 3 × 10-3 rem hr-1 at a distance of 1 m. What is the minimum distance from this source at which itis safe to work? After how long will it be safe to work at a distance of 1 m from the source?
