X-rays are immediately absorbed by:
Correct answer: D. Lead
- A. Aluminum
- B. Paper
- C. Copper
- D. Lead
Explanation
Dense substances are good absorbers of radiations like x-rays. They contain large electronic clouds and require a lot of energy to have their electrons knocked off. Hence, x-rays do not ionize these substances, instead, the radiations get absorbed by them. Out of the given substances, lead is a good choice of absorbers for x-rays as it is a very dense substance.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
