Irritants are typically thought of as chemical agents (for example phenol and capsaicin) but mechanical, thermal (heat), and radiative stimuli (for example ultraviolet light or ionising radiations) can also be irritants.
They form the legal basis for ionising radiation protection in the United Kingdom (UK), although work with ionising radiation is also controlled in the UK through other statutory instruments such as the Nuclear Installations Act 1965 and the Radioactive Substances Act 1993.
