Runoffs from an uranium mine stockpile have contaminated the surface water in a location. this might cause health problems among people in the location. which of these is the best plan to solve this problem? select one: a. plant trees around uranium mines to absorb contaminants b. put fences around uranium mines to check the flow of contaminants c. wear protective clothing for prevention against harmful effects of radiation d. collect the runoffs in retention ponds for isolation and recovery of contaminants

The best plan to solve the problem of health problems among people, because of the contaminated surface water is to collect the runoffs in retention ponds for isolation and recovery of contaminants. Correct D

This is tn eonly option from the given that is the most efficient and prodcutive way to solve this problem.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
