Polonium-210, the most lethal chemical element known to man!

Hello there!

To those unfamiliar with the bad boys of the periodic table, imagine Polonium as the worst bad guy. In fact he would most likely be the gang leader, considering it takes less than a microgram of this substance to constitute a fatal dose. To help you better image exactly how much a microgram is, it is about no larger than a spec of dust. But what exactly makes Polonium so deadly, that even a microgram could take out a healthy human being?

Let us back track a bit. Polonium 210 was first discovered as a radioactive chemical element (atomic number 84) in 1898 by Marie Curie. She found it in a source of Uranium and it takes the form of a solid metal with a silver color. Later winning a Nobel Prize in Chemistry for her discovery, she also a found another element, radium. They first saw the effects of how dangerous this element was after a lab accident exposed her own daughter to a fatal amount, evoking leukemia, which lead to her death 10 years later.
Another scandal brought attention to the perils of Polonium exposure with a Russian spy, Alexander Litvinenko, who was poisoned by a lethal amount, later dying of radiation sickness.
Medical News today sites, “Toxicologists estimate that one gram of polonium could be enough to kill 50 million people, on top of another 50 million who would become ill; in the case of Litvinenko, less than one millionth of that amount would have been enough to cause his death (less than a microgram).”
Polonium-210 is clearly very deadly to humans but strangely it does not itself have toxic chemical properties. The danger comes purely from the radiation the element emits. For someone to be infected with Polonium-210, they must absorb it internally. This can be through broken skin or through inhalation or ingestion, as in the Litvinenko case.
In the case of oral ingestion, polonium-210 is initially concentrated in red blood cells, and transferred to the liver, kidneys, bone marrow, gastrointestinal tract, and testicles or ovaries. Because it is a group 1 carcinogen, if inhaled it can cause lung cancer.

How to choose a DSLR:

Hello there, I have recently been writing only about reviews and I had an idea what if I write a blog on how to choose a DSLR for beginners. Most of my friends have the interest in photography but fail to choose which camera to go for. Some people at the end choose the camera which they are not satisfied of later. In order to solve such problems, I have come up with this blog, so that each one of us can decide what to go for. There are many aspects to be considered while choosing a camera. It completely depends upon what you are going to do with it and how much you are using it and on what occasions. Usually DSLRs are a bit expensive when compared to other cameras. I'd like to mention some of the aspects one has to consider while choosing them. What is your budget?: When buying a DSLR especially, the first thing you need to do is fix a definite budget. It can act as a barrier for your thinking and you will not decide to look at the more expensive ones. In the market...

Zoom Burst Technique

Hello there! In this post I have decided to blog on a photography technique called 'Zoom Burst'. This technique is used by photographers to highlight the given pin pointed object under focus. It is a highly skilled technique that requires at least a month of experience with a DSLR camera. The basic principle of this method is usage of lower shutter speeds to capture a trail of light which persists in the CMOS sensor of the DSLR camera. One needn't be a professional in photography to achieve these kinds of effects in the camera. Most of the people prefer to get these effects with the help of Photoshop or any photo editing software. But I personally believe that "the true spirit of photography lies in discovering new ways of seeing things, different from other people." One can truly enjoy his/her efforts in these fields of photography. I did get stunning results with this, but lacking time to perform more experiments, I satisfied myself with few pictures. St...
