Case Studies - Nuclear Holocaust

Nuclear Holocaust In Japan :

In 1945, two nuclear bombs were dropped on Hiroshima and Nagasaki cities in Japan. This holocaust killed about 100,000 people and totally destroyed the city. This Explosion emitted forceful neutrons and gamma radiations. The radioactive strontium (St*90) liberated in the explosion resembles calcium and has the property of replacing calcium in the bones. As a result large scale bone deformities occurred in the inhabitants of   these cities.


Chernobyl  Nuclear Disaster :

On April 26th 1986, the world worst nuclear explosion occured in one of  the  reactors in Chernobyl power plant in Ukraine. The disaster was caused mainly due to poor reactor design and human error. 


Impacts :

Chernobyl accident killed more than 20,000 people and 3.5 million people have suffered ill because of the accident. Nearly 1,35,000 people had to be evacuated at around Chernobyl.



Nuclear Accidents : 

Uranium Reprocessing :

Japan's worst nuclear accident  took place at a uranium reprocessing facility in Tokaimura, lbaraki prefecture, north east of Tokyo, Japan on September 30, 1999.


The accident occurred, when the workers were putting uranyl nitrate solution containing about 16.6 kg of  Uranium, which exceeded the critical mass, into the precipitation tank. Since the tank was not designed to dissolve this type of  solution, the workers and residents in the surrounding are exposed extremely to high level radiation.

ELECTRICAL COMPARATORS AND ITS WORKING

Electrical Comparators are used as a means of  detecting and amplifying small movements of a work contacting elements. An electrical comparator consists essentially of  a pick-up head or transducer for converting a displacement into a corresponding change in current and a meter or recorder connected in the circuit to indicate the electrical change, calibrated to show in terms of displacement. Generally, an amplifier is needed to provide the requisite sensitivity and to match the characteristics of different parts of  the circuit. Electrical comparators can be classified according to the electrical principle used in the pick-up head. Most of the comparators use either a differential transformer, an inductance bridge, a strain gauge or a capacitor as a means of detecting movement of the gauging element. There are different types of  electrical comparators. One kind called an electrolimit gauge is used to check or measure the outside diameter of a  roll. The objec...

SIMPLE CARBURETOR - CONSTRUCTION AND WORKING

CONSTRUCTION OF SIMPLE CARBURETOR :  The main Components of Simple Carburetor are : Float Chamber, float, nozzle, venturi, throttle valve, inlet valve, and metering jet . In the float chamber, a constant level of petrol is maintained by the float and a needle valve.  The float chamber is ventilated to atmosphere.  This is used to maintain atmospheric pressure inside the chamber. The float which is normally a metallic hollow cylinder rises and closes the inlet valve as the fuel level in the float chamber increases to certain level. The mixing chamber contains venturi, nozzle and throttle valve. The venturi tube is fitted with the inlet  manifold. This tube has a narrow opening called venturi. A nozzle is provided just below the centre of this venturi. The nozzle keeps the same level of petrol as that of the level in the float chamber. The mixing chamber has two butterfly valves.  One is to allow air into the mixing chamber known as choke valve. The other is to al...

TOP POLLUTION RECORDED IN WORLD

CHERNOBYL NUCLEAR DISASTER (NUCLEAR POLLUTION) :  In April 26,1986, the melt down of the Chernobyl nuclear reactor , in Russia, has leaked out the radioactive rays and radioactive materials.   Effects : 1. In this Pollution nearly 2000 persons have been killed by the accident. 2. People suffered due to the illness such as, degeneration of the cells, severe bleeding, anemia, skin cancer. 3. Animals, Plants are also affected by nuclear radiation.  MINAMATA EPIDEMIC (1953) : MARINE POLLUTION ( CASE STUDY ) Minamata is a small coastal village in Japan. The Chisso Chemical Company , which produces vinyl polymer plastics used organomercurial compound. The industry released its effluent into Minamata sea. The effluent containing mercury ions is converted into methyl mercury, which is highly toxic.  The marine organisms like phytoplankton and zoo-planktons easily absorb the toxic methyl mercury compound. These organisms are consumed by small fishes and these are in ...
