Question

Which of the following can cause cancer as well as cure it depending upon its intensity and use?
1. Tobacco
2. Alcohol
3. Ionized radiation
4. Ultraviolet rays

Answer 1

Correct Answer - Option 3 : Ionized radiation

The correct answer is Ionized radiation.

• Ionizing radiation can cause cancer as well as cure it depending upon its intensity and use.
• Ionized radiation:-
  • Ionizing radiation is typical energy that is released by atoms that would travel in the form of electromagnetic waves like X- rays and gamma ones or alpha, neutrons, or beta particles.
  • As radioactivity is nothing other than the spontaneous splitting of atoms, ionizing radiation would be the energy excess emitted in its due course.
  • From this activity, radionuclides are formed which are the unstable elements that would split and spread the ionizing radiation.
  • Most radionuclides are easily identified by the radiation type they emit, the energy of radiation, and also the half-life of it.

• Tobacco:
  • Tobacco is the common name of the plant Nicotiana tabacum and, to a limited extent, Aztec tobacco (N. Rustica) and the cured leaf that is used, usually after aging and processing in various ways, for smoking, chewing, snuffing, and extraction of nicotine.
  • Various other species in the genus Nicotiana are grown as ornamentals, known collectively as flowering tobaccos.
  • This article deals with the farming of commercial tobacco from cultivation to curing and grading.
• Alcohol:
  • Alcohol is any of a class of organic compounds characterized by one or more hydroxyl (-OH) groups attached to a carbon atom of an alkyl group (hydrocarbon chain).
  • Alcohols may be considered as organic derivatives of water (H₂O) in which one of the hydrogen atoms has been replaced by an alkyl group, typically represented by R in organic structures.
  • For example, in ethanol (or ethyl alcohol) the alkyl group is the ethyl group, ―CH₂CH₃.
• Ultraviolet rays:
  • Ultraviolet radiation is produced by high-temperature surfaces, such as the Sun, in a continuous spectrum and by atomic excitation in a gaseous discharge tube as a discrete spectrum of wavelengths.
  • Most of the ultraviolet radiation in sunlight is absorbed by oxygen in Earth’s atmosphere, which forms the ozone layer of the lower stratosphere.
  • Of the ultraviolet that does reach Earth’s surface, almost 99 is UVA radiation.
