http://www.bbc.co.uk/news/magazine-15288975 "The standard measure of the biological effect of radiation is the sievert. One sievert is a heck of a big dose, but one tenth of a millionth of a sievert, or 0.1 micro sieverts, is roughly the dose from eating one banana."

Translate this into 'film is dead' threats....

Cheers,

Link works.

So "eating one Banana" is the same as "sleeping with someone" twice ?

That does make you think, doesn't it.

I now have 10 years worth of film in my fridge. Wish I could say the same for Bananas. :angel:

Well, f*** that!

Don't you love risk assessment?

Some risks are worth taking. And if they're only half as bad as eating a banana...

Cheers,

I just bought some bananas...
Kids are off at school, wife left today to visit our son in Boston..it's me, the cat and a bunch of bananas for the weekend...

So, I was planning to flight to NY, sleep with someone after eating a banana, but now, knowing that it costs 401.5 miliwhatever, I will probably pass.
I am surprised the Nuclear Summicron is not measured.

Film?
It's dead.
In my freezer...
 
I'm trying to remember how many bananas I ate that day in 1961, when they wouldn't let us kids out to go play in the pink snow that suddenly fell on our town.
 
I undertake risk analyses for a living, mostly in unpredictable biological systems. What this article handily does is provide a real understanding that risk comprises a hazard (in this case radiation), a likelihood (how likely the hazard is to occur) and a consequence (what the outcome is likely to be). Risk lies everywhere. I was in Tokyo last month, I have toured the Chernobyl facility and I fly often. In relation to my long-term health, I am still more concerned that I spend most of my working life at a desk than I am about radiation.

The main difficulty most people face is a lack of impartial information on which to base their understanding of risk.

& going off at a tangent, bananas are good for cardiovascular health because of their potassium content: ~8-10 millimol per banana; generally we have too much salt (sodium) in our diets & too little potassium- salt promotes raised blood pressure. So Roger your risk assessment isn't complete if you ignore the K..

Interestingly, it's the potassium (specifically the radioactive isotope potassium-40) that's responsible for bananas having an above-background radioactivity level. And also responsible for your body having an above-background radioactivity level, for that matter. Actually, pretty much every living thing has above-background radioactivity for that reason: potassium is an essential element, so living things tend to concentrate it at above-background levels.

Some have theorized that the reason multicellular life evolved only when it did is that at the start, the level of K-40 in natural K was such that any multicellular organism would be prone to developing radiation-induced cancer and dying an early death until the level of K-40 eventually dropped to a non-hazardous level as a result of radioactive decay.
