If the monazite belt in Kerala is giving rise to natural radiation higher than the occupational exposure limits, why not cordon off the area and make a green belt in the area?
The dwelling areas of Kerala show natural background radiation level of 1408 – 1873 mGy/y which is much smaller than the occupational exposure limit. Some hot spots do occur, but there is no habitation near and around this place. Even if people visit these places, they would not stay for longer time in these places. Thus, the occupancy factor for these hot spots is much low and hence will not cause unduly high exposure. There is no need to cordon off this area.
