Abstract
Female offspring of gravid rats administered a single dose of 200 R of ionizing irradiation on Gestation Days 17, 19, or 21 remained significantly more active than similarly treated males. Both groups increased their activity over control levels with a lesser effect in evidence for 17 and 21 day males. Day 19 males were. unexpectedly, as active as the comparable female group.
