Question

Relative Biological Effectiveness (RBE) usually refers to the damage caused by
a. Radiation
b. Low temperature
c. High temperature
d. Pollution

Answer 1

Hint: The relative biological effectiveness is the ratio of doses of certain kinds of energy released with respect to others in the same amount of absorbed energy. The relative biological effectiveness can damage the tissues.

Complete Answer step-by-step answer:
Let’s discuss the above options and find the correct answer:
Radiation has an immense effect on the relative biological effectiveness because it transfers energy in many different ways. The value of relative biological effectiveness depends upon the ionization radiation relative to one other. The power of radiation can damage the components of the biological environment.
Hence, the correct option is A.

Additional information:
Low temperature does not affect the relative biological effectiveness as the low temperature does not change the power of radiation.
High temperature has not much effect on the relative biological effectiveness as it is related to the ionization radiation from the sun.
Pollution is the undesirable change in the surrounding environment which is basically caused by human activity and is very harmful to all humans, animals, and plants. Pollution can be in the form of chemical energy such as light, noise, etc. It is the introduction of harmful substances in the natural environment.

Note: If an individual absorbs a high dose of radiations of about 1 rad, it will destroy his tissue. The biological effectiveness depends on the source of energy of the radiation.The relative biological effectiveness is the ratio of doses of certain ionizing radiation with respect to another for the same amount of absorbed energy.
