Current Affair 1:

Background radiation in Kerala

 

News:

The present study found that the average natural background levels of gamma radiation in India were 94 nGy/hr (nano Gray per hour) (or roughly 0.8 millisievert/year).  The last such study, conducted in 1986, computed such radiation to be 89 nGy/hr. 

The higher radiation levels in Kollam are attributed to monazite sands that are high in thorium, and this for many years, is part of India’s long-term plan to sustainably produce nuclear fuel. Southern India, because of the presence of granite and basaltic, volcanic rock has higher levels of radiation from uranium deposits.

About Background radiation:

Background radiation, i.e., ionizing radiation present in the environment may be from natural origin or artificial/man-made sources.

Natural background radiation sources are cosmic rays and terrestrial sources, natural radioactive material such as radon from ground, building walls and floors, and traces of naturally occurring radioactive material in food and drinks.

Artificial or man-made origin includes radioactive fallout from nuclear weapons test and major nuclear accidents, medical diagnostic and therapeutic use of ionizing radiation, X-ray machines, particle accelerators, consumer products and transport of radioactive materials.

What is Babesiosis?

 

New research has revealed that the tick-borne disease 'babesiosis' is becoming much more common in the United States.  As per the recent CDC report, the research conducted from 2011 to 2019 shows that the cases of babesiosis have significantly increased in the north-eastern states. In particular, Maine, New Hampshire, and Vermont are being considered endemic.

What is Babesiosis?

Babesiosis is a life-threatening and severe disease caused by microscopic parasites that infect red blood cells. It is commonly caused to humans through deer ticks, which are also known as black-legged ticks.

While for many infected it might feel fine or do not have any dangerous symptoms, some can be vulnerable to the disease.
