Final answer:
The minimum distance a mobile radio transmitter may be operated in the vicinity of an electric blasting operation depends on specific circumstances and regulations in place to ensure safe operation. Factors such as power and frequency of the electric blasting operation determine this minimum distance.
Step-by-step explanation:
To ensure safety, a mobile radio transmitter should be operated at a minimum distance from an electric blasting operation. This is because electric blasting operations may produce electromagnetic waves that can interfere with the functioning of the radio transmitter. The minimum distance required will depend on factors such as the power and frequency of the electric blasting operation.
For example, if we consider the safe intensity of microwaves for human exposure to be 1.00 W/m², and a radar unit leaks 10.0 W of microwaves uniformly in all directions, we can calculate the distance required for safe exposure. Assuming that the power spreads uniformly over the area of a sphere with no complications from absorption or reflection, we can calculate the distance using the inverse square law.
In conclusion, the minimum distance a mobile radio transmitter should be operated in the vicinity of an electric blasting operation depends on the specific circumstances and regulations in place to ensure safe operation.
