Radiation protection

X-ray - a type of ionising radiation

Managing radiation hazards and using sources of radiation safely

These resources provide essential information and guidance for using sealed and unsealed radioactive sources or x-ray generating equipment, helping you comply with legislation and work safely.

Ionising radiation

Purpose: For maintaining records of worker registration, risk assessments, ordering, use and disposal of radioactive substances for activities on University premises.

Resource: Radioactive source database

Purpose: Contact information including emails and phone numbers for all University appointed school radiation protection supervisors.

Resource: Current radiation protection supervisors

Relevant for: Staff or students who will be dealing with radioactive materials

Purpose: Permission from The Environment Agency to use radioactive materials in the form of open sources for approved activities in specified premises.

Resource: EPR Permit Open Sources - University Precinct

Relevant for: Staff planning experiments using open sources of radioactive materials

External resource:

Purpose: Support for completing radiation risk assessments, which must be carried out before starting new work involving the use of radioactivity and must include suitable and sufficient assessments of potential radiation doses, in line with regulations.

How to use:

  • Consult your School Radiation Protection Supervisor if your experiment will use an isotope or activity that is not covered by an existing risk assessment.
  • Consult the University Radiation Protection Adviser / Radioactive Waste Adviser if you will require a new sealed or unsealed source or x-ray generator, new facilities or changes to existing facilities, or changes to existing University Health & Safety Executive (HSE) authorisations (notification/registration/consent) and Environment Agency (EA) closed (sealed) / open (unsealed) permits.

Resource: Radiation risk assessment guidance

Relevant for: Staff who will be completing radiation risk assessments

External resources:

Purpose: Highlighting the problems of self-decomposition when using and storing radiochemicals with methods to minimise this problem, covering:

  • factors affecting the rate of decomposition of radiochemicals labelled with tritium, carbon-14, phosphorus-32, phosphorus-33, sulfur-35, and iodine-125
  • ways to minimise the rates of decomposition
  • examples of classes of compounds

Resources: Presentations given by the University Radiation Protection Adviser / Radioactive Waste Adviser, to School Radiation Protection Supervisors:

Purpose: Detailing University procedures for the purchase, storage, use and disposal of sealed radioactive sources.

Non-ionising radiation

Lasers - an example of non-ionising radiation

These resources help you to comply with legislative and University requirements while protecting yourself and those around you from radiation safety hazards.

Purpose: For maintaining records of worker registration, risk assessments and use of lasers on University premises.

Resource: Laser user database

Relevant for: Staff needing to register as new users of lasers at the University and detail new laser equipment and working with laser risk assessments.

Purpose: Contact information including emails and phone numbers for all University appointed school laser safety officers.

Resource: School laser safety officers

Relevant for: Staff or students who will be working with laser

Information for using non-ionising radiation sources includes:

  • optical radiation such as ultraviolet (UV), visible and infrared
  • electromagnetic fields (EMFs) generated whenever electrical energy is used, such as power frequencies, microwaves and radio frequencies

Optical radiation hazards

  • Exposure to UV radiation from the sun can damage the cornea of the eye and the skin, causing redness, burns, accelerated ageing and potentially various types of skin cancer.
  • The misuse of powerful lasers can cause serious damage to the eye, including blindness, and produce skin burns.

EMF hazards

  • It would be rare for detrimental effects from exposure to high levels of EMFs to occur at the University, but the possible hazards include disruption to the central nervous system or increases in body temperature.

Purpose: Safety precautions for using microwave ovens, guidance on maintenance and testing, and responsibilities of University schools and services.
