2. Regulatory charge for the use of ionizing radiation

The regulatory charge for the use of ionizing radiation that requires a safety licence consists of a practice-specific basic charge and a source-specific sur-charge. If a safety licence covers more than one practice or radiation source, the regulatory charge shall be determined by adding together all the practice-specific basic charges and the radiation source-specific surcharges related to the licence.

The practice-specific charge category is determined based on the practice as follows:

Practice-specific charge category Practice
A Use of sealed sources
  Use of X-ray appliance (does not cover radiotherapy, nuclear medicine or dental X-ray practices using a panoramic tomography or dental X-ray device to image an in-mouth image detector, nor imaging a person with other than healthcare appliance)
B Trade in radiation sources
  Installation, maintenance and repair of radiation sources and manufacture of radiation appliances
  Transport of radioactive substances
  Practices in which orphan sources are repeatedly handled or stored
  Imaging a person with other than healthcare appliance
  Use of unsealed sources (does not apply to healthcare and veterinary medicine)
  Use of particle accelerators in industry and transillumination (excluding radionuclide production)
C Use of particle accelerators in research and radionuclide production
  Receipt, treatment and storage of radioactive waste when not part of another practice
D Use of unsealed sources in veterinary medicine
  Radiotherapy in veterinary medicine
E Nuclear medicine
F Radiation therapy

The radiation source-specific sur-charge is determined based on the radiation source and its use as follows:

Radiation source-specific charge category Radiation sources
A Dental X-ray appliance for imaging an in-mouth image detector
  Dental X-ray appliance in veterinary medicine
B Sealed source (other than a high activity sealed source). The charge is collected from a maximum of 100 sources.
  X-ray appliance (does not apply to X-ray appliance for healthcare, veterinary and industrial radiography or to X-ray appliances with separately built protection structures)
  Panoramic tomography device used in a dental X - ray practice
C X-ray appliance for industrial radiography or X-ray appliances with separately built protection structures (does not apply to healthcare or veterinary X-ray appliance)
  X-ray appliance in veterinary medicine (other than a dental X-ray appliance)
  X-ray appliance in healthcare (other than a panoramic tomography device for dental X - ray practice or dental X-ray device to image an in-mouth image detector) the use of which causes an effective dose of 0,1 mSv or less to the patient and no deterministic harm 1)
  Particle accelerator (does not apply to particle accelerators in healthcare or veterinary medicine)
  Unsealed sources in a laboratory when the amount of radioactive substance to be handled at one time is less than k ∙ 10 ∙ exemption value 2)
D X-ray appliance in healthcare (other than a panoramic tomography device for dental X - ray practice or dental X-ray device to image an in-mouth image detector) the use of which causes an effective dose of more than 0,1 mSv but 100 mSv at the most to the patient and no deterministic harm 1)
  Unsealed sources in a laboratory when the activity of radioactive substance to be handled at one time is equal to or more than k ∙ 10 ∙ exemption value but less than k ∙ 10000 ∙ exemption value 2)
  Unsealed sources in tracer tests elsewhere than in a laboratory
E High-activity sealed source
  Radiotherapy appliance in veterinary medicine
F X-ray appliance in healthcare (other than a panoramic tomography device for dental X - ray practice or dental X-ray device to image an in-mouth image detector) the use of which causes an effective dose of more than 100 mSv or the local or organ absorbed dose is greater than 10 Gy 1)
  Unsealed sources in a laboratory when the activity of radioactive substance to be handled at one time is equal to or more than k ∙ 10000 ∙ exemption value 2)
G X-ray superficial radiotherapy appliance
H Radiotherapy single-energy accelerator, X-ray deep radiotherapy appliance or afterloading appliance
I Radiotherapy multienergy accelerator

1) The effective dose to a patient from a single examination or procedure, including radiation exposure due to a radiation safety deviation.

2) The factor k is determined by the method of handling the radioactive material as follows: particularly high-risk work k = 0.1, treatment using conventional chemical methods k = 1, simple treatment k = 10 and storage k = 100. If different processing methods are used in the laboratory, then the fee category of the activity is determined on the basis of the processing method leading to the highest fee.

3. Regulatory charge for a practice causing exposure to natural radiation

The regulatory charge for a practice causing exposure to natural radiation is collected only if the practice requires a safety licence in accordance with section 148.

The regulatory charge consists of a practice-specific basic charge. If a safety licence covers more than one practice, the regulatory charge shall be determined by adding together all the practice-specific basic charges.

The practice-specific charge category is determined based on the practice as follows:

Practice-specific charge Practice
H Practice of aviation
I Practice in which workers are exposed to radon
  Practice in which workers are exposed to other natural radiation than radon or cosmic radiation
G Practice which causes releases of radioactive substances to the environment

4. Regulatory charge for the use of non-ionizing radiation

The regulatory charge for the use of non-ionizing radiation is collected for the use of a high-power laser equipment in the practices referred to in section 167 of the Radiation Act.

The regulatory charge consists of a practice-specific basic charge and a source specific sur-charge.

The practice-specific charge is determined as follows:

Practice-specific charge category Practice
A Use of high-power laser equipment (includes use of one high-power laser equipment permanently installed in one place)

The radiation source-specific sur-charge is determined based on the radiation source and its use as follows:

Radiation source-specific charge category Practice
E Movable high-power laser equipment
