This report presents average radiation doses received by the Norwegian population from different sources of medical radiation, cosmic radiation, and from naturally occurring and artificial radioactivity in the environment and food. Examples of population groups with elevated exposure are also presented.

In 2010, samples of sea water, sediment, and biota were collected in the Barents Sea, the North Sea, the Skagerrak and at a number of coastal stations and fjords. Data on radioactivity levels and trends in these areas are summarised in this report.

This report summarises some of the key findings from the activity of filling knowledge gaps in radiation protection methodologies for non-human biota, the GAPRAD project.

The Norwegian Radiation Protection Authority currently has five air filter stations located at various sites throughout Norway. The stations are important for surveying airborne radioactivity, and for the assessment and composition of any emissions in the case of mishaps and accidents. There are similar stations throughout Europe, and the inter-state collaboration makes it possible to track any emissions of radioactive substances.

The Norwegian Radiation Protection Authority is responsible for a nationwide network of 28 stations that continuously measure background radiation levels. The network was established in the years following the Chernobyl accident in 1986, and was upgraded to a new and modern network in the period 2006-2008. The purpose of the monitoring network is to provide an early warning if radioactive emissions reach Norway. The measurements from the network will also form an important part of the decision base for the Crisis Committee for Nuclear Preparedness in an early phase, once the news of the emissions has reached Norway.

Rapporten inneholder resultater fra overvåkningen av radioaktivitet i sjøvann og biota i 2005 langs norskekysten og i Barentshavet, Nordsjøen og Skagerrak. En oversikt over utslipp fra norske kilder og utslippsdata fra europeiske nukleære anlegg som er relevante for langtransport av radioaktivitet til norske havområder er inkludert i rapporten.

Denne rapporten gir en kort, men omfattende oversikt av virksomheten ved anleggene i Majak. Majak er per i dag det eneste anlegget i Russland som driver gjenvinning av brukt brensel i stor målestokk.

When the Chernobyl fallout reached Norway in spring 1986, national radiation protection authorities had over 20 years of experience in monitoring of reindeer herders in Kautokeino, northern Norway. This monitoring was initiated as surveillance of radiation doses to population groups being vulnerable to the fallout from the nuclear weapons testing in the 1950s and 1960s. The publication is in russian.

The 1986 Chernobyl accident was the worst nuclear accident in history. Norway was among the countries outside the former Soviet Union that received most radioakctive fallout from the accident. During the 20 years since the accident, extensive monitoring of radioactive contamination in foodstuffs such as dairy products, sheep, reindeer, game, wild mushrooms and freshwater fish has been performed. The publication is in Russian.
