Protagorass,

Radon 222 has a half life of 3.8235 days, but not being a pedantic twit I rounded up. If that is all you can resort to, you are pathetic.

Radium 226 has a longer half life, but is also an alpha emitter so is only dangerous if ingested or breathed, but as a solid is likely to remain in the earth. The radon gas (generated naturally) is breathed in and is more dangerous.

Have you any other useless information such as "the sun is brighter in the day"

Its good to see that you finally admitted that you are a cretin and decided to leave.

It looks like "chicken little" became a "little chicken".

While I have not the education of you two blokes I am following your posts with interest.
And I have no doubt, none, that we will use this power here.
I recorded Howe's speech and have watched it twice tonight, he is a man of the future.
And he is also right, I agree with his views about the left of my party too.
But feel no threat from them, if left to the left Labor would not govern in any state or territory and never in Canberra.
Nuclear power, as it is for so many country's, Will be in our future.
