RADIATION

HISTORY OF RADIATION

• Radiation was discovered by Antoine Henri Becquerel and Madam Curie

• They received Nobel Prize in the year 1903 for their Discovery of Radioactivity .

• Again she won Noble prize for discovery of radioactive elements polonium and radium

• The Irony is that both these scientists died because they were exposed to radioactivity which caused toxicity in their body

DIFFERENT TYPES OF RADIATION

X RAY RADIATION:This type of radiation occurs when a X ray photon collides with an atom .

Gamma Radiation:Gamma Radiation emission is a nuclear process that occurs when an Unstable nucleus of reaction excess energy is emitted in a nuclear reaction

Alpha Radiation:When two alpha particles(helium nuclei) collide with each other then certain amount of radiation is emitted , this radiation is known as alpha radiation.

Beta Radiation:• When two Tritium ions collide with each other to

form a helium atom then certain amount of radiation is emitted , this radiation is known as Beta radiation.

Neutron Radiation:When a slow moving neutron collides with Uranium then Uranium decomposes to give Barium and Krypton and a few neutrons ,this phenomena is known as Neutron radiation .

Ultraviolet Radiation:Ultraviolet light gets reflected by the ozone layer in atmosphere , this causes Ultraviolet Radiation

Ultravoilet Radiation causes Ultraviolet Radiation

ADVANTAGES OF RADIATION

Radiation is used in medical field :It is used in the process of diagnosis and TherapyIt is used in the process of chemotherapyIt is used in X Ray scanners .

Radiation is used in Research labs:NASA uses UV Radiation to identify planets present in farthest galaxiesRadiation is used as a Raw component in many toxic ExperimentsRadiation in communication field:All modern mobiles use different types of electromagnetic radiation

DRAWBACKS OF RADIATION

Despite being a very fast mode of transferring waves, if there are obstacles between the source of radiation and its destination, it'll affect the strength of the radiated wave depending on the 'penetrative power' of the obstacles, and the amount of obstacles.

Radiation waves are present everywhere in our everyday lives( radio waves, wifi, bluetooth, infra red, etc...) Ant these cause infertility and develop cancerous cells, with time.
