Question

Radiobiology (Actinobiology) refers to
a) Effects of radars on living organism
b) Effects of radio on living organism
c) Effects of radiations on living organism
d) Effects of satellites on living organism

Answer 1

Hint:Radiobiology is a branch of biology which deals with the study of the effects on the health of living organisms. It is both harmful as well as beneficial for living beings.

Complete answer:
To answer this question, we must know about the definition of radio biology and its effects.
Actinobiology is the combination of two words. Actin meaning rays and biology meaning study of life. Thus Actinobiology or radiobiology is the branch of biology which deals with the study of the effects of radiation on living organisms, especially the health benefits and hazards. Several kinds’ radiations are generally harmful and lethal to living things. They can cause severe burns or abnormalities and mutations which can be transferred to generations. For example ultraviolet radiations emitted from the sun can cause cancer.
Some non hazardous radiations are used for diagnosis and treatment of diseases. CT scan, ultrasound, X-ray involves the use of radiation for imaging of body parts. Effective radiation doses are given to the patients for cancer therapy.

Additional Information: Atomic bomb blast in Hiroshima and Nagasaki led to spread of massive radiations in the area. This harmful radiation has led to several abnormalities and diseases like cancer. The genes have undergone mutation which is inherited for generations.

Thus, the correct answer is (C) Radiobiology (Actinobiology) is the study of the effects of radiations on living organisms.

Note: The radiation therapy given to the patients in terms of a unit called Gray (Gy). The effective dosage is first calculated and then administered to the patients for therapy.
