#11), Roberto takes a good radiograph using: 10 mAs, 200 cm SID and a 5:1 grid this produces an exposure of 3 Gya. (4 poin 11a) What would the new exposure 8:1 grid while keeping mAs constant? ts) be exposure if she substitutes a 100 cm SID and an 11b) What should the new mAs value be to maintain exposure if she subst cm SID and an 8:1 grid? itutes a 100 #12) At 25 mAs and 400 cm SID the radiation intensity is 120 mR. (4 pts) 12a) What is the new intensity if the distance is 200cm and mAs is constant? 12b) What should the new mAs value be to maintain exposure at (120mR) at 200cm SID? #13 A good radiograph is taken with 25 mA, 200 ms, using a relative screen speed RS 300 and an 8:1 grid. Find the new mA value required to maintain exposure conditions if an RS 150 and 5:1 grid is substituted (time is constant). (4 pts)
