BIOGRAPHY OF MADAM CURIE

BORN ;7 NOVEMBER 1867 BIRTH PLACE;POLAND,EUROPE MARIE CURIE WAS MOST FAMOUS FOR DISCOVERY OF POLONIUM AND RADIUM. CURIE DISCOVERED POLONIUM AND RADIUM IN 1897 & SHE WAS AWARDED WITH FIRST NOBEL PRIZE IN 1903. SHE WAS AWARDED A SECOND NOBLE PRIZE IN 1911 FOR CHEMISTRY FOR HER WORK ON RADIUM AND ITs COMPOUND.IT IS THOUGHT THAT DUE TO HER LONG EXPOSURE TO RADIOACTIVE MATERIAL PRECIPITATED HER DEATH SHE DIED AT 4 JULY 1934 DUE TO BLOOD CANCER.

RADIOACTIVE DECAYRADIOACTIVE DECAYs ARE OF FIVE TYPE

PENETRATING POWER OF RADIOACTIVE EMISSION

ELECTRICAL PROPERTY OF RADIOACTIVE EMISSION

NUCLEAR CHAIN REACTION

NUCLEAR FISSION

IT SHOULD BE NOTICED THAT THE FISSION OF 1 GRAM OF URANIUM RELEASES AS MUCH ENERGY AS THE BURNING OF 2.5 TONS OF COAL.IN INDIA MAJORITY OF ELECTRICITY IS GENERATED FROM THERMAL POWER PLANT ABOUT 53% AND ONLY 3% OF ELECTRCITY IS GENERATED FROM NUCLEAR POWER PLANT

ELECTRICITY PRODUCTION IN INDIA

Nuclear power plant

THIS PROCESS IS CARRIED OUT NEAR THE SEA OR ANY WATER BODIES THAT IS AWAY FROM THE HUMANS AND IS DONE VERY SAFELY IN NUCLEAR POWER PLANT.NUCLEAR POWER PLANT CAN BE SIMPLY IDENIIED BY A SPHERICAL NUCLEAR REACTOR AND A COOLING TOWER17

NPPs in INDIA

THANK YOUWE HOPE THAT OUR COUNTRY & WORLD WILL GOING TO USE NUCLEAR ENERGY FOR MANKIND.ADVANTAGES OF NUCLEAR ENERGY.GENERATING ELECTRICITY.USED IN NUCLEAR SUBMARINES.USED IN MEDICAL APPLIANCESUSED IN IONIZATION AND MANY MORE
