Question

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?

Answer 1

please help

Answer 2

Is this multiple choice ?

Answer 3

plant trees around uranium mines to absorb contaminants

put fences around uranium mines to check the flow of contaminants

wear protective clothing for prevention against harmful effects of radiation

collect the runoffs in retention ponds for isolation and recovery of contaminants

Answer 4

I cant tell which answer is which can you space them out

Answer 5

plant trees around uranium mines to absorb contaminants




put fences around uranium mines to check the flow of contaminants




wear protective clothing for prevention against harmful effects of radiation




collect the runoffs in retention ponds for isolation and recovery of contaminants

Answer 6

i need this for final

Answer 7

You answers still arent spaced out i cant tell where a sentence begins and where it ends

Answer 8

plant trees around uranium mines to absorb contaminants.




put fences around uranium mines to check the flow of contaminants.




wear protective clothing for prevention against harmful effects of radiation.




collect the runoffs in retention ponds for isolation and recovery of contaminants.

Answer 9

Planting trees would not help most likley with the contamination they wouldnt even grow so A is definetly not a choice. Putting up fencing could possibly help. Wearing protective gear wouldnt be a soulution citizens wouldnt want to have to do that. The last one after the runoffs have been in the water you can just take it out its already into the water. So to me the best answer is to put up fencing to prevent anymore runoff contaminating the water.

Answer 10

thank you

Answer 11

The uranium itself has a very low level of radioactivity, comparable with granite. Virtually all the radioactive material from the associated minerals in the ore processed ends up in the tailings dam.

Answer 12

Wastes From Mining & Milling

In most respects, conventional mining of uranium is the same as mining any other metalliferous ore, and well-established environmental constraints apply in order to avoid any off-site pollution.

From open cut mining, there are substantial volumes of barren rock and overburden waste. These are placed near the pit and either used in rehabilitation or shaped and revegetated where they are. At Ranger mine, the development of the first orebody involved a waste to ore ratio of slightly over 2:1.

However, uranium minerals are always associated with more radioactive elements such as radium and radon in the ore which arise from the radioactive decay of uranium over hundreds of millions of years. Therefore, although uranium itself is not very radioactive, the ore which is mined, especially if it is very high-grade such as in some Canadian mines, is handled with some care, for occupational health and safety reasons.

Answer 13

Water
Run-off from the mine stockpiles and waste liquors from the milling operation are collected in secure retention ponds for isolation and recovery of any heavy metals or other contaminants. The liquid portion is disposed of either by natural evaporation or recirculation to the milling operation. Most Australian and many other mines adopt a "zero discharge" policy for any pollutants.

Process water discharged from the mill contains traces of radium and some other metals which would be undesirable in biological systems downstream. This water is evaporated and the contained metals are retained in secure storage. During the operational phase, such water may be used to cover the tailings while they are accumulating.
