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
