Relation to high absorption fraction of Tc sestamibi by kidneys in heart scan and these organs are
near to generation organs (Ovaries and uterus). Urinary system (kidneys and urinary bladder) are specified as
sources organs. The main object of this study is to determine the absorbed dose in these critical organs. we have
set amount of absorbed fraction radiopharmaceutical in position of kidneys and Urinary bladder in Rando
phantom in form of elliptical surfaces, then absorbed dose to ovaries and uterus measured by TLD-100 that had
set at position of these organs in Rando phantom. Results from ORNL phantom MIRD calculation TLD
measurement and Rando phantom simulation (MCNP) are comprised. The absorbed dose to uterus and ovaries
from urinary system for Rest are 0.139, 0.242 μSv/MBq and for Stress state are 0.105, 0.182 μSv/MBq,
respectively.
Key words: Absorbed dose, MCNP, MIRD, rando phantom, Tc-99m, TLD,
