Rradiation and Rradioactivity

I think we have to know that 'radiation' and 'radioactivity' is different.
(放射能=radiation 放射性物質=radioactivity)

We can know  'dose of radiation in the air' by checking geiger counter like this.

Radioactivity is carried by window and rain, then fall to the ground (river and see too).
Vegetables are contaminated  by radiation-contaminated soil, Fishes are contaminated by radiation-contaminated sea.
Cows, Pings and Chickens are contaminated by eating radiation-contaminated grasses on the ground.

If we eat radiation-contaminated vegetables, beefs, porks and chickens, we will be exposed radiation (internal exposure).

I am not paranoid about radiation dose in the air in Tokyo so far, but I am very careful to foods and drinks now.

I said I am 'very' careful, but some people don't mind it at all. People have different idea.

I am trying to do my best for telling accurate information, but my blog is just one of information source.  What you believe....it's your choice.
