Radiations are dangerous to living organisms because they damage the cell by:
- A
By producing ions in the cells
- B
By increasing the temperature of cells
- C
By decreasing the number of cells
- D
By destroying the cells
Radiations are damaging to living organisms because cause ionisation of living cells.
STB Pg-341
Hence, option A is correct.

STB Pg-341
Hence, option A is correct.
By increasing the temperature of cells—this is more related to thermal radiation. While heat can damage cells, ionizing radiation (like X-rays or gamma rays) causes damage through ionization rather than heating the cells.
By decreasing the number of cells—This is incorrect because radiation causes damage at the cellular level, potentially leading to cell death, but not directly by decreasing the number of cells.
By destroying the cells – Radiation can destroy cells, but the main mechanism is by causing ionization, which disrupts normal cell functions and can lead to cell death or mutation.
