X-ray technicians stand behind a shield when giving X-rays to patients because large doses of X-rays are known to cause cell damage and cancers.

Answer: D

Explanation:

Electromagnetic radiations like x-rays, alpha rays and other cosmic rays are harmful to human health and tissues to some extent when it is exposed for long time.

The x-rays are created when highly accelerated electrons hit the metal leading to ejection of electrons from its shell.

The x-rays are highly penetrate able but it cannot penetrate bones. So it is mostly used for getting scans of bones.

X-rays can penetrate cells and when exposed for large time in large doses it can harm the cell by damaging them or by creating cancer cells.
