What is Radioactive Polution?
Radioactive Substances and nuclear radiations (i.e., alpha, beta & gamma-particles) produced during nuclear reactions, affect our environment adversely and thus radioactive pollution is created.
Source of Radioactive Polutions & its effects
Source: Low level radioactive liquid wastes, radioactive gaseous wastes & dusts are released during nuclear explosions.
Effects:
I. The radiactive gaseous wastes are injected into the upper layer of atmosphere where, due to cooling they condense to fine-dust particles and thus Radioactive Cloud is formed. This cloud moves in the direction of the wind, settles down slowly to the surface of the earth & thus pollutes air,water & soil.
II. The radioactive substances produce energy which is so strong that the living cells are damaged or destroyed.
III. People working with radioactive elements develop tumours.
IV. Radioactive elements like strontium-90 affects our soil & through this human beings and animals are also affected adversely.
V. Nuclear explosions which are operated in sea, make sea water polluted. This affects the aquatic life.
VI. Among the radioactive radiations gamma-rays are the most dangerous, since they have high energy and high penerating power. These radiations can, therefore, pass freely in the human body, where they lose energy, which destroys the living cells by converting them into charged paticles i.e. ions. These ions are chemically very reactive & hence disrupt cell membranes, reduce the effectiveness of enzymes and even damage genes and chromosomes. All these results in diseases like Leakaemania & Cancer. 
VII. The radiations leaked from reactors damage the the health of human beings and animals.
Control Measures For Minimising Radioactive Polution:
The waste materials produced in the mining, enrichment and fission of U-235 inside the reactor are collective called Nuclear Wastes. At present most of the nuclear wastes are being stored in strong leak proof containers. These will be disposed off whenever a safe method of their disposal is found out in future.

Is there Gender Gap In Studies?
An International Study has shown that
¤ The number of girls who are studying maths as the subject of higher studies is very small compared to the number of boys.
¤The number of boys who go for Higher Studies in Biology is very small as compared to that of girls.
A number of reasons can be given for this –such as -
¤Parental Expectations
¤The fashion of the day
¤Lack of pressing need to go for an immediate job even if it is not glamorous
¤The Social Needs of Caring for a family which a career conscious man is always skipping – expecting the mother to take care of the children.
These are a few!! And the reason that – Biological Difference is the Cause , doesn’t hold water.
The reason is “Our” thoughts. Our Society and approach.
