D) Leucopenia
Show Answer
Answer:
Correct Answer: B
Solution:
Ionizing radiation is a type of energy released by atoms, that travels in the form of electromagnetic waves (gamma or X-rays) or particles (neutrons, beta or alpha).
The spontaneous disintegration of atoms is called as radioactivity, and the excess energy emitted is a form of ionizing radiation.
There are two broad categories of health effects: stochastic and nonstochastic.
Stochastic effects are associated with long-term, low-level (chronic) exposure to radiation.
Cancer such as leukaemia is considered as the primary health effect from radiation exposure.
Ionizing radiation’s ability to break chemical bonds in atoms and molecules makes it such a potent carcinogen and can cause mutations in DNA.
