The Zener effect is a type of electrical breakdown that occurs in a reverse-biased PN junction when the electric field enables tunnelling of electrons from the valence to the conduction band of a semiconductor, leading to a large number of free minority carriers which suddenly increase the reverse current.
Biological effects include both somatic and genetic effects. Since, somatic effect is given in the options, this option is not considered.
These effects such as skin burn, loss of hair, drop in white blood cells, and induction of cancer are examples of the somatic effects of radiation. These effects are related to the impact of ionizing radiation on living tissues and organisms.
Genetic effects include cancer, eye cataracts and abnormalities in future generations.
These effects such as skin burn, loss of hair, drop in white blood cells, and induction of cancer are examples of the somatic effects of radiation. These effects are related to the impact of ionizing radiation on living tissues and organisms.
