Abstract
Propagation of electromagnetic waves through space does not require any media like gases, water or solid matter. Radiations are colorless, tasteless and odorless. They are dangerous for human health. Our daily life appliances like cell phones, color televisions, computers etc emit different amounts of radiations. With the advancement of technology, radioactive rays have an important role in our daily life. X-rays are common example of radiations in medical fields. They are helpful in identification of diseases but their over exposure causes health issues.
There is no safe limit of radiations. However, a standard has been made that amount of radiations should not increase than 5.0 rem /year.
We can make ourselves safe from radiations by adopting following precautionary measures:
Ø Nuclear waste should be buried in proper places i.e away from populated areas.
Ø Persons working near radiations sources should wear proper dresses.
Ø They should visit doctors regularly.
Ø People should take part in cancer screenings according to recommended standards.
Ø People should adopt healthy habits.
