BRIEF EXPLANATION ON NUCLEAR HAZARDS

1. NUCLEAR
HAZARDS
YASHWANTH.T
1214216148

2. DEFINITION
Risk or danger to human health or the environment posed by radiation emanating
from the atomic nuclei of a given substance, or the possibility of an uncontrolled
explosion originating from a fusion or fission reaction of atomic nuclei .
This results in release of energy in the form of Gamma rays or Ionization particles
i.e alpha and beta particles

3. Alpha particles are fast moving positively charged particles .
Beta particles are high speed negatively charged electrons.
These energies have variable penetration power

5. SOURCES OF RADIO ACTIVITY
1.NATURAL SOURCES: Which includes cosmic rays from outer
space,soil,rocks,air,food etc,, which contains one or more radio
active substances
2.ARTIFICIAL SOURCES: These are man made and sources are
from nuclear power plants,nuclear accidents,X-rays etc,, where
radio active substances are used

6. EFFECTS OF RADIATIONS
Ionization radiations can affect living organisms by
causing harmful changes in the body cells and it also
changes the genetic level

7. TYPES OF DAMAGES
GENETIC DAMAGES: Genetic damage is caused by the
radiations,which tampers the DNA,there by affecting Genes
and Chromosomes. And this damage is often seen in off
springs and even transmitted to several generations

8. TYPES OF DAMAGES
SOMATIC DAMAGES: High doses of ionizing radiation result to
direct effect on the human body,but the amount of damage
mainly depends whether we are exposed with high dose in
short time or the same amount for long time.
"LATENT EFFECT"

9. CONTROL OF NUCLEAR POLLUTION
1. Nuclear power plants must be setted carefully with proper
studying
2. Proper disposals of wastes from the laboratory involving the
use of radioisotopes should be done
