Health hazards that are associated with uranium mining

Uranium is a radioactive substance that is used for generation of the thermal energy in the nuclear power plant. But uranium mining and processing is associated with numerous health effects related with the exposure to the radioactive decay products. The person may either inhale, ingest or the toxins can also seep inside the tissues through cut. The radioactive waste are responsible for causing drastic mutations and cancer.

<h3>What is Uranium mining ?</h3>

The process of removing uranium ore from the earth is known as uranium mining. In 2019, 53,656 tonnes of uranium were produced globally. The top three uranium producers are Kazakhstan, Canada, and Australia, who together produce 68% of the world's uranium.

  • The impacts of uranium mining are extensive, causing radioactive dust, radon gas, water-borne poisons, and higher background radiation levels in the environment. In order to produce nuclear energy and nuclear weapons, uranium must first be mined.

<span>The given mixture contains an </span>insoluble solid<span> <span>and an </span></span>aqueous solution of salt.  <span>The insoluble solid is </span>sand. <span>

First </span><span>we have to separate </span>insoluble solid. <span>Sand can be separated by doing </span>filtration. When we filter the mixture sand can be seen as the residue on the filter paper. 

<span>After filtering the mixture, we should collect the </span>filtrate. <span>Filtrate is the </span>salt solution. <span>By doing </span>evaporation <span>we can get the </span>solid salt. <span>

First </span>and second choices are wrong <span>because </span>after evaporating water filtration cannot be done and salt and sand will be mixed together.<span>

Salt cannot be filtered out because the salt is soluble and it is <span>in aqueous medium. Hence, third choice is wrong</span></span></span>

The period of a ripple on a lake is half a second. what is the frequency of the wave
Nataly_w [17]

Answer:

2 Hertz

Explanation:

<em>The frequency would be 2 Hertz.</em>

<u>The frequency of a wave is defined as the rate at which the particles of a medium vibrates when the wave is passed through it while the period of a wave is the time it takes the particles to make a complete cycle of vibration.</u>

The frequency of a wave is inversely related to its period and is defined by the following equation:

f = 1/t, where f is the frequency (in hertz) and t is the period (in seconds).

Hence, if the period of a ripple is 1/2 or 0.5 seconds, the frequency becomes;

f = 1/0.5 = 2 Hertz

Because of its high reactivity which element is normally obtained by the electrolysis
katrin [286]

<span>Lithium has a property of high reactivity and to obtain lithium is through electrolysis of its fused salts. Because lithium is very reactive, it is not found free so electrolysis is use to split it apart to get it.  Moreover, Lithium is an alkali metal with single valence electron that is easily given up to form cation, which make it a good conductor of heat and electricity.</span>
