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.

your comments that IFR technology is more completely developed compared to the
breeders.

comparable to that from Indian PHWRS. In India, price of power is by law
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!

can power the world for centuries on the uranium that's already been mined --
and with no more uranium enrichment needed, ever.
