Question

Why is ionizing radiation dangerous and what type of tissue is most likely to be seriously affected by it.

Answer 1

When atoms in living cells become ionized one of three things usually happen – the cell dies, the cell repairs itself, or the cell mutates incorrectly and can become cancerous. Not all cells are affected by ionizing radiation in the same way.

The tissues most affected by radiation are those that undergo rapid replacement, such as bone marrow, the lining of the gastrointestinal tract, and skin.
