Question
What is the exposure to indoor radon in Finland?
Answer
Obs | Exposure parameter | Population | Exposed fraction | Background | Exposure | Description |
---|---|---|---|---|---|---|
1 | Population average | Finland | 1 | 5 (4 - 9) | 100 (95 - 105) | Kurttio Päivi, 2006: STUK otantatutkimus |
2 | Guidance value for new apartments | Finland | 1 | 0 | 200 | STM decision 944/92 for new apartments http://www.finlex.fi/fi/laki/alkup/1992/19920944 |
3 | Guidance value for old apartments | Finland | 1 | 0 | 400 | STM decision 944/92 for old apartments http://www.finlex.fi/fi/laki/alkup/1992/19920944 |
Page-specific entries (indices that have exactly one value each for the whole variable; usually mentioned in the title and/or in the scope):
- Pollutant: Radon
- Exposure route: Inhalation
- Exposure metric: Annual average indoor concentration
- Exposure unit: Bq/m3
Rationale
- The answer is based on Seturi project.
Maaperän radonpitoinen ilma tunkeutuu asuntoon talon alapohjassa olevien rakojen kautta. Maaperän lisäksi radonia erittyy huoneilmaan talon alla olevasta kalliosta ja täytemaasta, sekä laatan ja kantavien rakenteiden mineraalipohjaisista materiaaleista. Myös porakaivovesi voi olla sisäilman radonin lähde.

Exposure route: Inhalation
Exposed population
Whole population:
- Best guess = 5307690
- Min =
- Max =
Average exposure of those who are exposed
Altistumisarvio perustuu STUKin uusimpiin sisäilman radon-mittauksiin Suomessa. Suomalaisten asuntojen radonpitoisuuden keskiarvo (+/-SEM)
- Best guess = 100 Bq/m3
- Min = 95 Bq/m3
- Max = 105 Bq/m3
Background concentration (outdoors)
- Best guess = 5 Bq/m3
- Min = 4 Bq/m3
- Max = 9 Bq/m3
Unit
Bq/m3
