A hitherto unknown phenomenon oi
radiation which may have far-rraehing i'm
plications for the future the restorative
effect OF ordinary lisht--has been reported
TO the National Academy Of Sciences
When micro organisms moulds. bacteria
and the like~~are irradiAted with ultra.
violet light, they are killed or lose their
ability TO reproduce After few days few
recover.
This recovery rate can be increased as
much as 400 o00-fol by irradiaton with
ordinary light Immediately after the ultra
violet treatment according 10 the expert
ments reported by DR.. Albert Kelner Of the
Carnegie Institution OF Washington There
is practically no recovery al all when the
organisms are kept in tho dark.
Light Is Restorative.
The invisible ultra.vio rays In Some
way disrupt the vital process Of the single
celled organisms which are comparable 10
the cells which compose the bodies of higher
animals and which reproduce In essentially
the same way, Something In visible hEhs
restores the vital organization
The powerful action Of light on The re-
suscitation Of the ultra violet treated cells
leads us to hope thA! further study Of this
phenomenon may lead to discovery Of fac
tors causing similar recovery from X-irra-
diation or iiradiation from radioactive
materials. There is thus the possibility OF at
least partial physiotherapy Of radiation in
jury" DR.. Kelner says,
Among the effects Of ultraviolet radia-
ton is production of a large number OF
mutations Cells continue TO divide but new
lines of heredity are set UP, This can be
almost entirely prevented by the visible
light treatment DR. Kelner says,
