Radiation is an energy transmission, which has electric-magnetic waves .We all are exposed to radiation in day today life. Examples are sun, emitting ultaviolet rays infrared , microwave ovens. Mobile ,Transmission tower and background radiations or cosmic rays Xrays and Gama rays. Radiation risk depends upon it wave length and penetratibility. Broader the waves ,lesser is penetration . Smaller waves have stronger power and penetration
TYPES OF RADIAION It is mainly divided into two parts 1- Non-Ionising Radiation ,which is lower energy radiation, not enough poweful to seperate electrons from any atoms or molecules, in matter or living organisms. Its energy can make the molecules vibrate and produce heat, like microwave ovens . 2- Ionising Radiation carries more more energy than non-ionsing and they can ionize the atoms and molecules and break their bonding .It can detach electrons from atoms or molecules, which causes changes at the atomic level . Such changes usually involve the production of ions.That is why it is called ionizing radiation.
Radiation from Mobile Mobile has now become the part and parcel of everyone’s life. In fact it is now one’s identity and means of communication , bank, entertainment, diary and what not. Be aware that it is also a continuous source of radiation. Although it is of very low grade radiation. Although mobile’s short time use is insignificant.But it’s long time use has cummulative effect and is definitely harmful to the body. Harmful effects of Mobile radiation are. Headache, stress ,fatigue ,disturbed sleep, insomnia, compromised immunity, memory loss, fertility problems. Higher doses may cause mental problems and even cancer.
Test your Mobile’s radiation level by dialing *#07#.It’ll tells SAR/mobile radiation value. 1.6W/Kg is the maximum threshold value of radiation level. It should be below 1.6Watt/Kg.If it’s more than that, change your mobile phone or take necessary steps .
In high doses, ionizing radiation can damage or kill cells ,cause mutation in the organs in the body or even cause death. This kind of radiation has many beneficial uses, such as in energy production, in industry, in research and in medical diagnostics and treatment of various diseases, such as cancer.
USES OF RADIATION
- 1-In MEDICAL FIELD Used extensively as diagnotic tools , as Xrays of the body parts and In CT scans ,Radioisotope study ,PET SCAN. Therapeutic uses are in treating cancers. Thanks to radiation, 2- For Production of Power – By Nuclear power palnts Energy: radiation allows us to produce electricity as nuclear energy.
- 3-In Industry and Science–Industry and science: with nuclear techniques based on radiation, scientists can examine objects from the past or produce materials with superior characteristics in, for instance, the car industry. uses
- 4-In Packaging of syringes and surgical materials like cather canula are directly strilized after packing ,by high dose radiation.
- 5-In Food Processing industry – To irradiate packaged food materials , fruits and vegetable to, prevent them from infection and rotting. . Radiation is thus a two way sword .What a irony , It can cause cancer ,It can treat cancer
