Radioactivity is a nuclear phenomenon
Radioactivity is exhibited only by elements of mass number greater than 206
The radioactivity of an element is affected by electric and magnetic fields in the surroundings
Radioactive substances emits three types of radiations, a-rays, \(\beta\)-rays and y-rays
The radioactive element is transformed into a new element

guys the answer is not C magnetic field affect radioactivity
the correct answer is B
The answer is C. Natural Radioacgivity is not affected by external surroundings factors
The correct answer should be C , because radioactivity is not affected by electricity or magnetic field.
the answer is c
though magnetic field can affect the trajectory of charge,it does not affect the decay itself
Nuclear reactions unlike chemical reactions is not affected by external factors like temperature etc....
Characteristics of Natural Radioactivity:
Natural radioactivity is a purely nuclear phenomenon. The nucleus of a radioactive substance is unstable and such an unstable nucleus undergoes spontaneous breakdown (disintegration). The process continues until a stable nucleus is obtained.
Myschool, pls the answer is C
External forces do not affect natural radioactivity, it only affects the particles being emitted.
