.. . I started in to make a number of these lamps, but I soon found that the x-ray had affected poisonously my assistant, Mr. Daily, so that his hair came out and his flesh commenced to ulcerate. I then concluded it would not do, and that it would not be a very popular kind of light, so I dropped it...

1934 : Time –dose factor concept
Henri Coutard showed
that both skin and
mucosal reactions
depended on the dose,
the treatment time
and the no. of
treatment sessions.

Francois Baclesse
1967 : Concept of Dose –volume Relationship
Hypothesized that in
addition to time-dose
factor , irradiation
damage to normal
tissue also depends
upon the volume
irradiated.
