The biological risk for the first person than the second as a result of radiation weighting is 10 times.
<h3>
What is radiation weighting factor?</h3>
As stated in the question, radiation weighting factor (q) is the ability to transfer energy to the body.
If radiation factor of proton = 2, and radiation factor of alpha particles = 20.
- First person is exposed to alpha radiation = 20
- Second person is exposed to protons = 2
Risk of first person with respect to second person = 20/2 = 10 times higher

The reaction equation is:
<span>2CuO(s) + C(s) </span>→ <span>2Cu(s) + CO</span>₂<span>(g)
First, we determine the number of grams present in one ton of copper oxide. This is:
1 ton = 9.09 x 10</span>⁵ g
We convert this into moles by dividing by the molecular mass of copper oxide, which is:
9.09 x 10⁵ / 79.5 = 11,434 moles
Each mole of carbon reduces two moles of copper oxide, so the moles of carbon required are:
11,434 / 2 = 5,717 moles of Carbon required
The mass of carbon is then:
5,717 x 12 = 68,604 grams
The mass of coke is:
68,604 / 0.95 = 72,214 g
The mass of coke required is 7.22 x 10⁴ grams
