The methods work because radioactive elements are unstable, and they are always trying to move to a more stable state. This process by which an unstable atomic nucleus loses energy by releasing radiation is called radioactive decay.
Postgraduate Taught (MSc) Our taught postgraduate courses are based around lectures, with problem classes and computer workshops.
Full details of departmental research interests are available on our Research pages.
Undergraduate (BSc) The department has three undergraduate degrees that involve the applications of statistics to the social sciences and include a range of statistical and mathematical subjects.
In principle, any material of plant or animal origin, including textiles, wood, bones and leather, can be dated by its content of carbon 14, a radioactive form of carbon in the environment that is incorporated by all living things.
Because it is radioactive, carbon 14 steadily decays into other substances.
