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.

An older unit of radioactivity is the curie, Ci, which was originally defined as "the quantity or mass of radium emanation in equilibrium with one gram of radium (element)". [22] Today, the curie is defined as 3.7 × 10 10 disintegrations per second, so that 1 curie (Ci) = 3.7 × 10 10 Bq.
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).
In 2002, there were about 57 million deaths. In 2005, according to the World Health Organization (WHO) using the International Classification of Diseases (ICD), about 58 million people died. [1] In 2010, according to the Institute for Health Metrics and Evaluation, 52.8 million people died. [2]
