a

Irradiation time for tibiae from two and four month old animals.

b

Irradiation time for tibiae from one month old animals.

c

EOI: End of Irradiation Time is the specific time the sample exited the reactor. All samples and standards were decay corrected back to this time.

d

Count position was in a rotating position 2.5 cm from the detector face.

e

Count position was in a stationary position 2.5 cm from the detector face.
