Radiation

The task of the Radiation Protection and Radiation Monitoring Office of the Environmental Board is to ensure the safety of humans and the environment from the possible harmful effects of ionizing radiation.

Ionizing radiation is the transfer of energy, directly or indirectly, as ion-generating particles or electromagnetic waves with a wavelength of 100 nanometers or less.

Humans are exposed to ionizing radiation in two ways, from:

  • From natural sources - cosmic radiation, gamma radiation from the ground, radon decay products in the air and various radionuclides that occur naturally in food and drink, as a person is constantly exposed to ionizing radiation in his normal and clean living environment.

  • From artificial radiation sources, or human activities - used in various fields such as medicine, veterinary medicine, industry, science and services - for treatment, diagnosis, scientific purpose, sterilization or monitoring of some industrial process. Also radioactive contamination from the testing of nuclear weapons in the atmosphere and the release of radioactive releases from the nuclear industry into the environment.

Radiation activities

Radiation activities and permits

Radiation activity is any activity which increases or may increase human exposure from artificial or natural radiation sources and may require a radiation practice license.

Radon

Radon is a naturally occurring radioactive gas in the environment. Radon surveys conducted in Estonia and methods for measuring radon levels indoors.

Personal dosimetry

Under the agreements, the measurement service of personal dosimeters is provided using an accredited measurement method. National dose register for radiation workers and dose card for foreign workers.

Radiation monitoring and crisis management

Management of the national radiation monitoring and early warning system. Radiation emergencies and response.

Radiation services

The Environmental Board provides various paid services ensuring radiation safety related to its core business.

Main tasks:

  • Following the national radiation monitoring program.

  • Managing the early warning system and informing the public about potential dangers.

  • Issuance of radiation practice licenses.

  • Issuance of a radiation expert certificate

  • Recognition of a Contracting State 's Radiation License

  • Provides radiation services

Humans are exposed to ionizing radiation in two ways, from:

From natural sources

Natural sources of radiation include cosmic radiation, gamma radiation from the ground, radon decay products in the air, and various radionuclides that occur naturally in food and drink because a person is constantly exposed to ionizing radiation in their normal and clean living environment.

From artificial radiation sources or human activities

Used in various fields such as medicine, veterinary, industry, science and service - for treatment, diagnosis, scientific purpose, sterilization or monitoring of some industrial process. Also radioactive contamination from the testing of nuclear weapons in the atmosphere and the release of radioactive releases from the nuclear industry into the environment.
