Terahertz Rays Can Be Use For Human Body As Well As For Security Purposes.

If you are found of James Bond type of movies, you might have seen special telescope like instruments used for spying purposes. These hand-held instruments are capable of x-raying the rooms and buildings made of stone and concrete. Most of the times these are used by the hero to check how much ammunition is in the building while hero is sitting on the top of the hill.


Well you will be surprised that in reality it is not possible to make use of x-rays through that much small machines. X-rays help in detection of problems in a live body or used in some security equipments but they are quite lethal for human body.

To coup this problem, scientists are working on another type of rays, which are called terahertz rays. These are harmless to body. In a simplest language, terahertz range between lower limits of infrared and upper of microwave. Terahertz are not only less harmful for body but also very helpful in detecting plastic objects, which x-rays can’t do at all. As they can detect lot more objects than the x-rays, they  can be very useful for security purposes.

The technology for Terahertz or T-rays is quite complicated. It has some side effects but its advantages are more than its disadvantages. Scientists are working on this new technology so that we may be able to use this technology with minimum cost and minimum side effects.
