Three types of sources of ionising radiation are used at the university: open sources, sealed sources, and x-rays.
Lasers are used in the University for many different research and teaching applications. We control all work with class 3B, 4, and other laser classes by following a Laser Management Protocol.
Some work with radio and microwaves is controlled (subject to safety control measures) and you will need to follow our procedures when using these in order to keep yourself and those around you safe.
These pages are concerned with static magnets – i.e. those that emit a magnetic field of their own, as opposed to electromagnets which require electricity to produce a field.
Ultraviolet (UV) radiation is electromagnetic radiation of a wavelength between 100nm (nanometers) and 400nm. This is less than the wavelength of visible light, so you cannot see UV radiation.
