Does radiation poisoning children differently than adults?

In order to accomplish the rapid growth and development that occurs in children, cells must replicate at a higher rate than in adults. Cells that divide more frequently are at greater risk of injury due to radiation. Children are therefore more vulnerable to radiation poisoning than adults. If a child survives an episode of radiation poisoning, they are also more likely to develop radiation-induced cancers due to a combination of more frequent cell division and a longer lifetime.
