Question # 1

What are isotopes?What do they have common and what are their difference.

Ans 1: Isotopes are such nuclei of an element that have the same charge number Z but have different mass number A.It means,in the nucleus the number of protons is the same but the number of neutrons is different.

Question # 1

Define absorbed dose and Gray.

Ans 1: Absorbed dose:It is defined as the amount of energy absorbed from an ionizing radiation per unit mass of the absorbing body i.e.
Absorbed dose=energy/mass
Gray: it is defined as the amount of energy equal to one joule absorbed by a body of mass 1kg i.e
gray=1 joule/1 kg

Question # 1

Differentiate between controlled and uncontrolled reaction.

Ans 1: To maintain a sustained controlled nuclear reaction,for every 2 or 3 neutrons released ,only one must be allowed to strike another uranium nucleus.it is called controlled chain reaction.
Ans 2: If more than one neutron produces further fission then it will grow uncontrolled and called uncontrolled chain reaction.
