There is actually a bit of literature about permissible doses of coffee in
terms of sports drug testing.

This includes differences between US and International MPC (sounds familiar)

To be objective, it is best for interested readers do do their own searches

have fun

Dear Maury,

I knew that Mr Dunster was no more. He came to India once. He was an eloquent 
speaker with total command over Queen's English! he was known for rapid fire 
animated talk and quick repartees.He played a significant role in drafting ICRP 
1990 document. Listening to him, elucidating the intricacies of radiation 
protection philosophy was an overwhelming experience.

I wish I could give more details on the reference in which Mr Dunster calculated 
the permissible daily volume of coffee! Incidentally, if my recollection is 
correct consumption at the recommended volume has added benefits. At that 
volume, coffee consumption is reported to reduce heart attack according to 
research published in the latest issue of CIRCULATION HEART FAILURE JOURNAL. It 
was all a matter of coincidence!

Regards
Parthasarathy

Dear Parthasarathy
rnal!
Have not yet found what you wished (not finished yet) but did come 
across an interesting bit of Health Physics Society/Society for 
Radiological Protection history at:
https://en.wikipedia.org/wiki/Society_for_Radiological_Protection

Also, "John Dunster CB, a former President of the SRP, died in April 
2006 at the age of 83. John had been a pioneer of modern radiation 
protection and was an acknowledged giant of the radiation protection 
profession. ..".

Best,
Maury&Dog

number. Can any one who has access to old Volumes of Health Physics locate that 
page and send me a scanned copy? I believe that he was news editor of the 
journal during late 60s.

breeders.

administered  by the Central Government. In the case of nuclear power the Atomic 
Energy Act 1962 gives Central Government an enabling provision to decide power 
tariff. So talking about the cost of power in India is only an academic 
exercise!

not have a telephone in India will have to book a call at a telephone exchange 
to talk to another subscriber a few hundred miles away and wait for his turn. 
Now there is an explosive growth in mobile phone technology. Fifty years ago we 
did not think that we would be able to carry a telephone exchange in our 
pocket.Telephone service between India and USA has almost become too cheap to 
meter!

accumulated, as Peter suggests, and we probably will (but it will take a while 
to get going).  Using the plutonium from used LWR fuel as the essential catalyst 
to get started, fast reactors such as the IFR and its ilk (PRISM, TWR, 4S, etc) 
can power the world for centuries on the uranium that's already been mined -- 
and with no more uranium enrichment needed, ever.
