Before the earthquake and tsunami which hit northern Japan in March, 2001 (2011?), with regards to public perception, nuclear energy had slowly been making somewhat of a revival. However, the melting fuel rods and radiation leaks at Japan’s Fukushima Daichi nuclear plant has had an adverse impact on how nuclear technology is perceived. There is a growing consensus that nuclear technology can not only reap enormous profits but can also pose a great threat to life on earth. 

It is universally acknowledged that nuclear energy, which does not discharge any atmospheric emissions (is this what you meant?), is widely used within our current society due to the tremendous amount of energy it yields. However, in addition to the energy produced, the generation of nuclear power also creates an enormous amount of radioactive materials which have the potential to cause great harm to life on Earth. Even though safety precautions are taken in nuclear plants, radiation cannot be isolated completely. The Fukushima Daichi accident caused by the tsunami is a prime example for us to reflect on whether it is worthwhile to use nuclear energy so extensively. 

Nuclear magnetic resonance spectroscopy is a powerful and theoretically complex analytical tool used in medicine. Radiation therapy is one of the few effective methods to cure cancer. Unfortunately however, this process can also harm patients. Generally speaking, radiation therapy can cause great pain and also has a very low success rate. 

The greatest risk that nuclear technology poses is in its potential use for military purposes. To date, enough atomic bombs have already been built to completely destroy the planet. If a war were to start with these bombs, the entire Earth could be destroyed. Many countries already have the technology required to make atomic bombs. I am not optimistic it will be possible to control this situation. (Is this what you were trying to express?)

As can be seen, nuclear technology is a two-edged sword, having many good and bad aspects. There is no denying that nuclear technology is conducive to life, however, it may be prudent to use it to a lesser extent for the sake of human existence and the safety of our planet. 

I will be taking the IELTS and I am really worried about my writing and speaking. Please help me with my compositon, any corrections will be welcome! Thank you very very much!

Hi Qing,

I hope I haven't put words in your mouth. Please double check this and ensure that it corresponds with what you were trying to express. I was really only focusing on the language aspects of your essay and not the factual elements.

Hope this helps. I think your English ability is quite impressive! Good luck with your exam!!

Kind Regards,

Giri
