The curie (symbol Ci) is a non-SI unit of radioactivity originally defined in 1910. According to a notice in Nature at the time, it was to be named in honour of Pierre Curie , [ 1 ] but was considered at least by some to be in honour of Marie Curie as well, [ 2 ] and is in later literature considered to be named for both.
The reports say for years Chelyabinsk dumped about 120 million curies of radioactive waste to give ... in 1957 said to be on of the world's worst ever, a drought and strong winds blowing ...
Deadliest animals as of 2016 [1]. This is a list of the deadliest animals to humans worldwide, measured by the number of humans killed per year. Different lists have varying criteria and definitions, so lists from different sources disagree and can be contentious.
We know this from the Life Span Study, which followed survivors of the atomic bombing in Japan during World War 2. [5] [4] Over 100,000 individuals were followed for 50 years. [5] 1 in 10 of the cancers that formed during this time was due to radiation. [6] The study shows a linear dose response for all solid tumors. [6]
Radioactive contamination, also called radiological pollution, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids, or gases (including the human body), where their presence is unintended or undesirable (from the International Atomic Energy Agency (IAEA) definition).

The severity of the radioactive fallout was played down, and the release of a highly dangerous isotope during the fire, Polonium-210, was covered up at the time. [ 35 ] Partly because of this, consensus on the precise number of cancer deaths caused in the long term as a result of the radiation leak has changed over time as more information on ...
