sorry sorry, that was just frivolous .. won't happen again (but it was just there asking for that!)

I refer to the post by Sarnian.

“With a half-life of 30 years (hence an eighth-life of 90 years) once you have it, you have it for life.”

This is not so. The biological half-life following ingestion is quoted as 70 day1 or 100 day2 a very much shorter period.

Muck3 has reported in detail on the decrease in Cs-137 and other radionuclides after nuclear fallout. A decrease in radio-activity in plant or animal may be expected from the following processes:

• Radioactive decay
• Weathering (wash-off , leaching and loss of plant parts).
• Dilution due to plant growth
• Transfer to non-edible or non-useable parts of the plant
• Removal from root layer of soil by transfer into deeper layers or other geo-physical factors acting on the soil.
• Continuing fixation of radionuclides in the soil.

In the first three months after the Chernobyl accident the activity (in terms of effective half-life in days) for a number of commodities was grass 10.5d; lettuce and spinach 4.2d; milk 33.4d

A long term decreases of Cs-137 concentration in various foods over subsequent years was reported by Muck.

You should know that the major source of Cs-137 or Sr-90 to the environment was from atmospheric atomic testing estimated to be about 100 times greater than the release from Chernobyl.

One other thing what do you mean by an eighth life of 90 years?

Do any of you really want to drink the water, or eat food irrigated by it, after its been through a nuclear power plant?

Be honest now NIMBY's.

There are other practical ways to make electricity.

Hey sausage,

Just for a minute (attention span issues), let's say nuclear power is no longer an option for Japan and all those other countries that presently use it in their back yard.

What "other practical ways" do you suggest?

Green faith being exposed again. Don't expect any invitations from the National Broadcasters Professor Wade but your integrity is more important. Thanks.

An interesting article, though I would personally have liked more data- such as the amount of radiation from safe degrees of sun exposure (and how much would prove excess) in correspondence to how the 200Bq/L in water would supposedly not impact a person (which, either which way of looking at it, is still quadruple the radioactive mass of a whole adult person being added on top of the 50 already in one person's body).
Without something like this we really can't actually gauge how serious or non-serious a 200bq/L intake would actually be.
