Consider the following statements regarding ionizing radiations:1. The...
Statement 1: Ionizing radiations include long wavelength ultraviolet radiations (UV), X-rays, and gamma rays.
This statement is incorrect. Ionizing radiations do not include long wavelength ultraviolet radiations (UV). UV radiation falls in the non-ionizing radiation category, as it does not have enough energy to remove electrons from atoms or molecules.
Statement 2: Electrically charged particles produced in nuclear processes can knock electrons out of atoms or molecules, producing ions.
This statement is correct. Ionizing radiations consist of particles or electromagnetic waves that have enough energy to remove electrons from atoms or molecules, resulting in the formation of ions. These charged particles can be produced in nuclear processes, such as radioactive decay or nuclear reactions.
Statement 3: Gamma rays passing through a cell can ionize water molecules near the DNA, potentially causing DNA to break and damage living tissues.
This statement is correct. Gamma rays, which are a type of ionizing radiation, have high energy and can penetrate cells. When they interact with water molecules near the DNA, they can ionize the water molecules, causing the formation of reactive oxygen species and free radicals. These reactive species can then damage the DNA molecules, leading to genetic mutations and potentially harming living tissues.
Conclusion: Out of the three given statements, only statement 1 is incorrect. Ionizing radiations do not include long wavelength ultraviolet radiations (UV). Therefore, the correct answer is option 'A' - Only one.

Consider the following statements regarding ionizing radiations:1. The...
- Ionizing radiations: Electromagnetic radiations such as short wavelength ultra violet radiations (UV), X-rays and gamma rays and energetic particles produced in nuclear processes, electrically charged particles like alpha and beta particles produced in radioactive decay and neutrons produced in nuclear fission, are highly damaging to living organisms. Hence, statement 1 is not correct.
- Electrically charged particles produced in the nuclear processes can have sufficient energy to knock electrons out of the atoms or molecules of the medium, thereby producing ions. The ionizing radiations cause damage to biological systems and are, therefore are pollutants. Hence, statement 2 is correct.
- A gamma ray passing through a cell, can ionise the water molecules near the DNA. These ions might react with the DNA causing it to break. They can also cause chemical changes by breaking the chemical bonds, which can damage living tissues.Hence, statement 3 is correct.
