[ RadSafe ] Blood Irradiatora: X-rays versus Cs-137

[John Jacobus]

Salah,
I have never seen an x-ray blood irradiator.  (I have
seen blood irradiated using a medical treatment
accelerator, but that was due to the limited need for
sterilized blood at that facility.)  Apparently, there
are some x-ray units for sale.

As for Cs-137 irradiators, they are very simple units
to operate, use less electricity, and, I would expect,
require less maintenance.

1.  Either type is shielded so that exposure to staff
is minimal, if non-existant. 

2.  There will be initial cost, but with x-ray
irradiators there may be more for maintenance and
repair.  With any unit, you should look into a
maintenace contract.

3.  All units should be able to deliver about 25 Gy to
the blood.  

4.  I would expect that operational costs of the
Cs-137 irradiators to be lower than that for the x-ray
type.  

One consideration you did not mention was security
against terrorists.  We have had to deal with that
issue, so it is not insurmountable issue.
