a

Gender-independent organ doses for newborn, 1-year, 5-year, and 10-year phantoms were tabulated from male phantom since male and female phantoms have identical anatomy except gender-specific organs.

b

Gender-specific organ doses were calculated separately from male and female phantoms.

c

Effective doses were calculated using male and female organ doses as recommended by ICRP. Effective dose for 15-year phantoms was tabulated in 15-year female columns.

d

Male organ doses are not available (NA) for 15-year female phantom. Female organ doses are not available for 15-year male phantom.
