Re: R: Environmental dose levels in Italy

[Ernesto_Faillace@notes.ymp.gov]

Speaking of hills:  L'Aquila is at an elevation of 714 m  (2300 ft) a.s.l. and
is surrounded by high mountains.  I was surprised to see that Rome (which is
built on 7 very low hills) is reported at twice the dose rate!  However, Rome is
situated in a volcanic region (there are several crater lakes in the vicinity),
whereas L'Aquila is in a region of tectonic (earthquake) activity.  However, I
am still surprised that the cosmic ray component in L'Aquila would be so weak
compared to the terrestrial component in Rome.

It is correct to assume units are mSv?  Florence is in the hills - 77 mRem
(0.77 mSv) appears a little low.  Here is Louisiana, which is almost at sea
level, we average between 0.90 and 1.25 mSv per annum.  any comments?

Hi Bob,

from my files the naturale external doses yearly adsorbed by peolple are:

Florence  0.77
L'Aquila  0.82
Naples    2.13 (there is the Vesuvio)
Perugia   0.90
Potenza   1.31
Roma      1.58

It depends on presence of vulcanic activities on these areas (obviously
higher in Naples area and northern Sicily)
