Concerning the measurement value “cpm” of the survey meter, for example, radioactive contamination is determined for an area if a value twice the usual background level is detected. The background level where measurement by a survey meter was performed is 25 to 40 cpm. Further, as a reference for measurements in becquerels, naturally occurring radioactive potassium K40 is on the order of 33Bq/kg for white rice, 1600Bq/kg for dried kelp, and 66Bq/kg (dry weight, excluding water content: 165Bq/kg) for the human body. Therefore, when comparing the measured values with these reference values, I think that you will come to appreciate the extent to which the specimens on display have been contaminated by radioactive particles.

What question would you ask to the next photographer we will interview? How do we promote a photography culture? This is a very important because photography culture is not as strong as music or movies or sports. How can we get the attention from the ordinary people? This is very important.
