Behavioural analysis of irradiated mice. A, Buried Food Pellet test measures the latency to find a food pellet. A significant impairment was found 24 hours post X-ray irradiation (F(4,34) = 2.754, p = 0.0437, n=5 mice). B, Habituation/Dishabituation test measures the amount of time spent in investigating a new odour, strawberry and coconut. A significant impairment was found 24 hours post X-ray irradiation in the identification of coconut, while for strawberry this impairment is only seen after 1 week (F(4,27) = 2.540, p = 0.0629, n=5 mice; (F(4,31) = 5.724, p = 0.0014), n=5 mice respectively). * p ≤ 0.05.
