Question : 4
Which city receives the highest cosmic radiation amongst the following ?
a) Mumbai
b) Delhi
c) Kolkata
d) Chennai
Answer »Answer: (d)
The total annual external dose from sources in soil and cosmic rays in Mumbai, Kolkata, Chennai, Delhi and Bengaluru is 0.484, 0.81, 0.79, 0.70 and 0.825 milligray respectively. Gray is a unit for absorbed dose; when the radiation energy imparted to a kg of material is one joule, it is called a gray.
Since gray is very large, milligrays (one-thousandth of a gray), and microgray (one-millionth of a gray), are commonly used. Cosmic rays come from outer space. Their intensity at a place depends on the altitude. Cosmic rays alone contribute 0.28 milligrays at the first three cities as they are at sea level; the column of air helps to reduce their intensity.
At high altitudes, the protection from the column of air is less. The cosmic ray contributions are higher at 0.31 milligray and 0.44 milligray respectively at Delhi and Bengaluru as these cities are at altitudes of 216 metres and 921 metres. Air passengers receive 5 micrograys per hour from cosmic rays. Parts of Kerala and Tamil Nadu are high background radiation areas (HBRA) because of the presence of large quantities of monazite in the soil.
Thorium content in monazite ranges from 8-10.5 per cent. Researchers found that the radiation levels in 12 Panchayats in Karunagappally varied between 0.32 to 76 milligrays per year; the levels in 90 per cent of over 71,000 houses were more than one milligray per year.

It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into sun-synchronous orbits, a service that was, until the advent of the PSLV, commercially viable only from Russia. PSLV can also launch small size satellites into geostationary transfer orbit (GTO).
The PSLV has launched 55 satellites/spacecraft (26 Indian and 29 Foreign Satellites) into a variety of orbits so far.
Note: The Polar Satellite Launch Vehicle, commonly known by its abbreviation PSLV, is an expendable launch system developed and operated by the Indian Space Research Organization (ISRO).
On Feb 15, 2017 PSLV-C37 Successfully Launches 104 Satellites in a Single Flight.
