Ionising Radiation


Ionising radiations (IR) occurs as either electromagnetic rays (such as X-rays and gamma rays) or particles (such as alpha and beta particles). IR occurs naturally (e.g. from the radioactive decay of natural radioactive substances, such as radon gas and its decay products) but can also be produced artificially.

There is a prescriptive set of environmental and safety regulations that our processes and procedures address.  These include, but are not limited to:

  • Appointment of key radiation pretention roles including a Radiation Protection Advisor (RPA) to provide expert advice to the University and Radiation Protection Supervisors (RPS) in specific areas, wherever ionizing radiation is used.
  • Produce local rules for each area involved in radiation work.
  • Obtain appropriate permits and provide appropriate notifications to the regulators.
  • Provide training to staff who work with radiation.
  • Monitor potential exposures to employees who work with radiation.
  • Overall governance provided by the Radiation Safety Committee.
  • Dispose of radioactive waste in line with University permits.
