How Is Nuclear Energy Harmful?

.Nuclear energy is one of the leading sources of power in the United States, but along with all of the benefits that come with nuclear energy, there are also disadvantages. These disadvantages can be harmful to people, the environment and the world as a whole.



.Function


Before you can understand how nuclear is harmful, you must understand the process that goes into creating nuclear energy. First, uranium must be gathered and put through an enrichment process to get it ready for nuclear reactors. The uranium is then put through "fission." Fission is the splitting of an atom and this is the process that actually creates the radioactive material and gives off radiation. That fission process creates a chain reaction between all of the uranium and the heat from this process turns water into steam. That steam spins the turbines and generators to create electricity.


Features


The radiation that is released into the air is harmful to many living things. There is natural radiation that comes from our homes, bodies, and televisions, but the radiation from nuclear waste can add more and create enough to become harmful. If a person is exposed to enough radiation, mutations can occur, mostly to newborns. This includes humans and animals. Unless there is a nuclear disaster or the waste gets into the wrong hands, the everyday exposure from outputted radiation is hardly noticeable.


Considerations


Everyday operations in a nuclear plant cannot cause widespread damage, but there are few things that can spread it quickly. Nuclear meltdowns and explosions send radiation into the air at a rapid pace. One of the biggest disasters in history was the Chernobyl explosion. Many lives were lost due to the radiation and mutations occur among newborns around the area as well.


When nuclear power is contained, it is a relatively safe procedure, but when the nuclear power gets into the wrong hands, nuclear weapons can be created. Nuclear weapons are a large aspect of terrorism and the use of nuclear weapons can be harmful to large areas of land.


Effects


Radioactive waste also spreads through water that is used at nuclear reactors. This has a huge effect on the surrounding aquatic life and can even cause mutations in fish. Swimming is banned in any water around nuclear plants because the radioactive waste in these waters could be potentially deadly to humans.


Prevention/Solution


In order to stop the amount of harm that nuclear energy causes, there are a few steps the government can do. The first is to find proper storage for the radioactive waste. Some prospects have been looked at, but a permanent solution needs to be found to keep people safe. The other step is to seize any nuclear weapons that could mean disaster for the whole world. If the nuclear weapons are destroyed, they cannot be used to inflict harm.

atomic tecnology

When the photographs and video footage of Pakistan's nuclear tests
were released, the Pakistani public was struck by awe with the

powerful glow which illumined the mountain under which the explosions

took place. Though this was partly a photographic trick, which

highlighted the infrared (or heat) energy that the explosion

generated, it was still an austere and ominous preview of what a

nuclear explosion can do. From casual conversations with citizens

around the country soon after the tests, I gained an impression that

most Pakistanis think of nuclear weapons as just another more powerful

kind of weapon. The magnitude of even a modest nuclear explosion has

not yet surfaced to cognition in most minds.

So let us try and recount what actually happens when a nuclear bomb

explodes, such as the 13-kiloton bomb which exploded over Hiroshima in

1945. Although this was a very primitive nuclear device, it managed to

kill over 45,000 people within 24 hours of the blast and several

generations continue to languish as casualties.

Unlike conventional explosives which rely on the energy generated by

chemical combustion, nuclear weapons rely on the extreme energy which

is generated when an atomic reaction takes place in which one element

is converted into another element (for example when hydrogen is

converted to helium). The difference in the energy which is generated

is immense. For example a sphere of plutonium about the size of a

cricket ball is capable of producing an explosion equivalent to 20,000

tons of TNT. There are basically three types of nuclear bombs which

have been developed. The first kind are atomic bombs which use

fission reactions, or the splitting of atomic nuclei to generate

energy. This is the kind of bomb which was dropped by the Americans on

the Japanese cities of Hiroshima and Nagasaki in 1945. The second

variety are thermonuclear devices which use an atomic trigger and a

uranium jacket to start a fusion reaction in which lighter elements

such as hydrogen are forced to undergo a fusion reaction to combine

and form a heavier element. The energy liberated from 0.5 kg (1.1 lb)

of hydrogen-isotope fuel is equivalent to that of about 29 kilotons of

TNT, or almost three times as much as from the uranium in an atomic

bomb. The environmental impact of both these bombs would, however, be

similar though the magnitude would be greater in the case of a

thermonuclear device. The third kind of nuclear weapon is the neutron

bomb which is a modified thermonuclear device that does not have a

uranium jacket and thus reduces the chance of widespread radioactive

fallout. The neutrons generated from the thermonuclear device can,

however, generate radioactivity within a small impact radius, killing

life but without causing widespread fallout destruction to buildings

and infrastructure (the neutron bomb is thus a tactical weapon).

wall.e

it is great movie for every one.
wall.e movie tell us how technology is effecting our world and it remain like this for 50 years then what can happened with these people and with this world.
so any one who want to be entertained and want to learn sum thing have to watch this movie,

it will change his or her life or atleast his/her way of thinking.
this poster seems to be boring but infact it is great movie.
must watch.

technologies effect childrens

Technology is the downfall of our children. Look at all the ailments children now have due to inactivity because of technology.



Do you see kids outside playing tag, or other childhood games that would be seen up to & including the early 80's?


Granted they can find almost anything in a few moments on the internet & they can keep in touch with friends/family around the world in moments, but obesity is running rampant & childhood diseases are at an all time high due to all these video games, iPods, computers, cable & sateliite channels.


when i was a kid I was outside EVERY DAY playing softball, stick ball, wiffle ball, punch ball, roller skating, tag, fox & hounds & so many other things.


Now you rarely see children outside. It's a shame that technology is such a sharp double-edged sword.

I.T Technology

As the big developed companies have lot of data to manage, so they also have to take lot of computers and as number of computer increases then there should have lot of energy and for that purpose you have to make a lot of energy through burning fosils or oil and as you burn the oil so the heat start flowing into the enviorment and so that enviorment goes warmer and warmer. On other hand you have to make lots of cool rooms for that computers and generators also emit gases in the enviorment so that it causes increase in the temprature of the enviorment.
If it remain like this the temprature of the world will increase so much that for our childrens it will be impossible to live here so start thinking about your offspring so that they can live healthy life here. 

Do we know the impact of technology on enviorment?

it is my question that do we know the impact of tachnology on enviorment?

yes we are aware from the impact of technology on the enviorment, but why are not trying to stop it.

it is because of the fact that the owner of the companies are very powerful and they dont let us to stop this activity. There is also a fact that most of the are not aware from this fact. so it is our responsibility to let people know of this fact.

using of a technology or suicide

we are using cars for our easiness but how this facility is effecting our enviorment? have you ever think about it?
using of technology is just like as we are getting a benefit and giving ours life in that reward, so it means that we are commiting suicide
its not our enviorment
but it is my enviorment
because we are the part of this enviorment
so think positvely for this world so we can able to live in this world in future
