Providing that you put flowers and/or garden plants contaminated at a level of 54.1 kilobequrels(kBq)* 1 meter away from you for 2 months, the estimated radiation dose is 0.003 millisievert (mSv).

*54.1 kBq is the maximum contamination level of vegetables (spinach/ kilogram) ever detected (in Fukushima prefecture).

This level is quite low compared with 2.4 mSv a year, the average natural exposure to radiation of the world.

 

 ** The exposure to radiation is categorized as internal exposure or external exposure.
     The exposure from the flowers is external exposure.
