i dont know the answer of your question correctly
Answer:
at distance 18.33 ft no biological effects
Explanation:
given data
distance = 41 ft
radiation = 5 rem
to find out
how close get so no biological effects
solution
we know here that intensity of radiation R is inversely proportional to (radiation)²
so here equation will be
.............1
here I is intensity
so here I1 = 25
because for 0 to 25 there is no detectable effects and for 25 to 100 it will . temporary decrease so
we take 25 because dose is less than 25 so we take that highest value
so


R1 = 18.33 ft
so at distance 18.33 ft no biological effects
