Answer:
correct option is C. 1700 - 2300
Explanation:
solution
according to Care stream, exposure indicators provide the technical adequancy incident radiations on the x ray
and we muse care stream formula that is
Exposure Index EI = 1000 × + 2000
here 1 mR = 2000 EI
and 2 mR = 2300 EI
and 3 mR = 1700 EI
so here acceptable range of exposure indicators is 1700 - 2300
correct option is C. 1700 - 2300
