Common Radiation ExposuresSource of exposure Dose in rem Dose in sievert (Sv)

Exposure to cosmic rays during a roundtrip airplane flight from New York to Los Angeles

3 mrem 0.03 mSv

One dental x-ray 4 – 15 mrem 0.04 – 0.15 mSv

One chest x-ray 10 mrem 0.1 mSv

One mammogram 70 mrem 0.7 mSv

One year of exposure to natural radiation (from soil, cosmic rays, etc.

300 mrem 3 mSv

Summary

• Our results show:• no influence from the nuclear power plant

„Temelin“ to the environment according to our measurements

• the value of radiation is increased on asphalt roads or close to big rocks

The project was funded from the budget of the International Visegrad Fund´s program “Small Grants” No. 111 400 83

and supported by the Southbohemian Region, municipality of the town Veselí nad Lužnicí and group ČEZ a.s and Bukovská voda.
