RE: Effective Irradiation Dose Unit-UV

["Fulmer, Philip" <FulmerP@ttnus.com>]

Ken,

I have had to dig way back in the cobwebs of my memory, but an Einstein
is a mole of photons (i.e., Avagodro's number of photons equals 1
Einstein).  So the article that you read is giving the number of photons
of 253.7 nm wavelength impinging per unit area.

Best regards,

Philip

Subject: Effective Irradiation Dose Unit-UV


Radsafers,

I came across a unit of "effective irradiation dose" for UV in the 253.7
nm
 region.  This unit is the nano-Einstein/mm2.  This unit was used in a
paper published in Biochemistry in 1977.  The unit as used in the
article,
relates moles of ATP joined per mole of enzyme.  Any info on this unit?
