Radiation safety

Work and research involving radiation is required to be according to Swedish law, ordination and regulations from the Swedish Radiation Safety Authority (Strålsäkerhetsmyndigheten, SSM). This applies both at Karolinska Institutet (KI) and Karolinska University Hospital (K).

Any staff member, student and affiliated researcher who’s work involves radiation is obliged to attend the mandatory courses and apply the protective measures listed below for each type of radiation.

Ionizing radiation

Radioactive substances (open/sealed radioactive sources)

Before implementing a new method involving a radioactive substance, a research group/core facility shall 

  • request a local license from the radiation protection expert (see Contact)
  • delegate a radiation protection assistand (see Documents)
  • fill in the radiation risk assessment RADRA (see Documents).

Work and research involving radioactive substances requires the mandatory courses listed below.

  • Web course Introduction to radiation protection (see Course link)
  • Teacher led course Open radioactive sources (see Course link)
  • Practical introduction at the isotope laboratory with the radiation protection assistant
  • Review the radiation safety instructions at KI (see Regulatory documents)

The radiation protection assistant shall also complete the courses listed below.

  • Web course Radiation protection assistant.
  • Web course KLARA radiation registration.
  • Practical introduction with the radiation protection representative of the facilities (see Contacts).

X-ray

Before implementing a new method involving an equipment that can emit X-rays, a research group/core facility shall 

  • inform the radiation protection expert (see Contact)
  • delegate a contact person, who shall ensure preventive maintenance and radiation safety checks according to manufacturer recommendations
  • fill in the radiation risk assessment RADRA (see Documents).

Work and research involving the X-ray equipment requires the mandatory courses listed below. 

  • Web course Introduction to radiation protection (see Course link)
  • System specific web course
    • X-ray irradiator  (see Course link)
    • X-ray imaging system  (see Course link)
    • Dental X-ray imaging system (request access, see Contacts)
    • Other X-ray systems (contact the radiation protection expert)
  • Practical introduction at site with the contact person of the X-ray system
  • Review the radiation safety instructions at KI (see Regulatory Documents)

UV light

Before implementing a new method involving an equipment that can emit ultraviolet (UV) light, a research group/core facility shall 

  • inform the radiation protection expert (see Contact)
  • delegate a contact person, who shall ensure preventive maintenance and UV safety checks according to manufacturer recommendations
  • fill in the radiation risk assessment, form RADRA (see Documents).

Work and research involving a UV system requires the mandatory courses listed below. 

  • Web course Basic UV safety
  • Practical introduction at site with the contact person for the UV system

Guideline values for UV exposure can be found in SSM's regulation 2008:48 (see Links).

Laser

Before implementing a new method involving an equipment that can contains a laser, a research group/core facility shall 

  • inform the radiation protection expert (see Contact)
  • delegate a contact person, who shall ensure preventive maintenance and laser safety checks according to manufacturer recommendations
  • fill in the radiation risk assessment, form RADRA (see Documents).

Work and research involving a laser system requires the mandatory courses listed below. 

  • Web course Basic laser safety
  • Practical introduction at site with the contact person for the laser system

Nuclear holding

Before implementing a new method involving nuclear substances (containing Uranium or Thorium) a research group/core facility shall 

  • inform the radiation protection expert (see Contact)
  • delegate a contact person, who shall ensure fulfilment of KI's instructions for nuclear safeguards
  • fill in the radiation risk assessment, form RADRA (see Documents).

All work and research involving nuclear substances shall attend the mandatory course moments listed below.

  • Web course Nuclear holding at KI (see Course link)
  • Review instructions for nuclear safeguards at KI (see Regulatory documents)

Nuclear holding at KI requires fulfilment of regulations from both the Swedish Radiation Safety Authority and Euratom 302/2005 (see Links).
