Re: Wart Removal

[D J Hornsey <bssdjh@bath.ac.uk>]

  Dear Lew et al.
         A query about dosimetry for the X-rays you used in the past to
treat the above skin condition. The reason for my query is my attempt to
dose unfiltered X-rays. You say you used a Victoreen condenser R-meter to
dose almost unfiltered 35 kVp X-rays. I'm not familar with the meter but
would it have allowed you to dose the very low photon energies that you
were probably interested in to treat the skin condition? Does anyone know
of a perhaps more modern instrument that can be used for dosing the
so-called  'Grenz' rays?

  Regards,

    David Hornsey
