I think Japanese people (especially people live in Tohoku and Kanto area) have had to think about 'External exposure' and 'Internal exopsure' (to radiation) since Fukushima daiichi accident.
Exposure to radiation must be thought by total of amount; external and internal.
I am not paranoid about 'external exposure very much now. You understand it when you read this post.
I can check sieverts by geiger counter.
However I should be careful about internal exposure too.
Internal exposure... it means we have to avoid foods and drinks that are radioactively-contaminated.
In March, Radioactive iodine found in Tokyo, Saitama, Chiba, Yamanashi, Gunma and Tochigi water supply
The iodine level in Tokyo was 210 becquerels per liter at the Kanamachi purification center which serves Tokyo's 23 central wards, along with Musashino, Machida, Tama, Inagi and Mitaka cities.
(I am living in Musashino.)
100 becquerels is the maximum level considered safe for consumption by infants
Radioactive iodine has not been detected since 28th March, but Tokyo waterworks department says that 'not detected' means less than 20 becquerels per 1 kilo gram.
According to the guidelines for drinking-water quality by WHO, they set 10 becquerels per 1 kilo gram.
Btw, I haven't drunk tap water since 14 or 15th March. I've drunk bottled water and used it for cooking.
Some people do same as me, but not so many people. Many people don't mind it (except people who have infants.)
Because I am worrier, I'm not going to change this lifestyle, at least for 2-3 months.
I do not want to increase total amount of exposure as possible as I can.
'Be careful about water'- is one of way to avoid internal exposure, but it's just my idea because there are many people in Tokyo who don't care about it at all.
Not drinking tap water...is inconvenient for me (not only me but also Japanese ppl), but if you have got used not to drink tap water, life in Tokyo may not be so inconvenient for you.
If you go/stay to(in) Kansai, Chugoku, Shikoku and Kyushu area, I don't think you have to worry about this issue so far.
（Radioactive iodine were not detected in the areas.)
