- 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?26- Identify the device which requires external electrical energy source. a. Thermocouple b. Thermistor c.
