Electrons Used for 100 Per Cent
Sterilization by Makers of Drugs
By DELOS SMITH
United Press Science Editor
Kalamazoo, Mich. U.R; The
extremely difficult puzzle of how
to achieve 100 per cent sterili
zation is being solved now in an
extremely simple way. Or, rath
er, it is simple because we're
living in the atomic age.
Sterilization here means ab
sence of bacteria. When you coa
sider that bacteria are both in
visible and everywhere, you un
derstand why science now con
siders sterilization a "relative"
matter that there is rarely if
ever any such thing as 100 per
cent sterilization.
But now the atomic particles
called electrons are being used
. on a commercial and therefore
i practical basis to achieve the
100 per cent, at least theoretic
ally. The substances being ster
ilized by electrons are drugs.
First, you seal drugs into a
container bottle or plastic en
velope. Then you put the con
tainer into a stream of electrons
traveling at 175,000 miles a sec
ond which gives them a charge
of 2.000,000 electron volts.
That's all there is to it. Fast-
moving electrons pass through
the "containers like light through
a window. Any bacteria which
may be inside are killed. Since
the container is sealed, no more
can get in. Thus 100 per cent
sterilization becomes quite sim
ple in this new "by-product"
way of the atomic age.
Electrons traveling at 1,700,
000 miles a second (20,000,000
electron volts) will split atoms
and release the awesome and
frightful power of radioactivity.
At much lower rates, electrons
power television tubes. At 175,
000 miles a second they're in
stantly fatal to bacteria but do
nothing to atoms.
.That's important with drugs.
If electrons broke into their
atoms, the composition of the

with the help of seven teen-age
counselors, will conduct swim
ming, canoeing, sailing, moun
tain climbing, camp craft and
nature study.
Boys wanting to attend the
camp who are without the neces
sary fee may earn it by selling
soap, Jones said. Two boys,
Jimmy Johnson, 230 North Ivy
St., and Mike Kline, 1691 Grand
ave., both 10, earned their camp
lee of S18 by checking out 72
boxes of soap apiece Thursday
night, and had them sold by
Saturday afternoon, just in time
to register for camp. Jones
added that earlier last week,
during a special Day's Adventure
trip sponsored by the YMCA, the
boys had learned of the pro
gram from a friend. Until then
they had no way of earning camp
money. Jones said. Both are
now at Diamond lake.
A few openings are still left
for the next two camp periods
starting Aug. 1 and 7, Jones
said. Each period is limited to
50 boys.
Brooks Boy Injured
By Shotgun Blast
Salem (U.R) A 12-year-
old Brooks, Ore., boy was in
fair condition at a Salem hospi
tal today after being wounded
in the chest bv an accidental
shotgun blast Sunday.
James Dennis Harris, was
wounded by a 12-gauge weapon
that accidentally fired when he
tripped and fell against it while
the gun was leaning against a
trailer. The boy and his three
brothers were shooting at tar
gets when the accident oc
curred, according to state police.

drug would be changed and
there might be radioactivity. The
research laboratories of the Up
john Company, a leading manu
facturer of pharmaceutical prod
ucts for the medical profession,
spent five years developing a
completely safe and effective
sterilization by electrons tech
nique. Ointments Sterilized
It is now sterilizing with elec
trons two ointments used by
physicians in treating eye and
ear infections. Ointments are
very hard to sterilize by the
three conventional methods
heat, by the addition of bacteria-killing
chemicals, or by
filtration. And the closest possi
ble approximation of 100 per
cent sterilization is particularly
important.
Dr. Richard S. Schrieber, vice
president and director of re
search, said the electron method
was "feasible" for sterilizing any
phamaceutical product. Not all
products require a theoretic 100
per cent sterilization and some
are susceptible to theoretic com
plete sterilization by the older
methods.
However, Upjohn has a Fed
eral Drug Administration okay
to sterilize such antibiotics as
pencillin with electrons. Schrie
ber left the impression that the
method will be applied to more
and more drugs as facilities are
increased. The electron accelera
tor now in use can sterilize only
100 drug units a minute, which
pass through its electron beam
on a conveyor belt.

Chevrolet's advanced
oversquare design. It means
less friction . greater

engine life!
Here are more dollar-saving reasons why new
Chevrolet trucks offer you the most modern
V8's your money can buyl
MODERN 12-VOLT ELECTRICAL SYSTEM
You get double the punch for quicker
starting (up to 30 percent faster cranking
speed) and more efficient ignition for finer
performance. Also, you have a greater re
serve of electrical power.
GAS-SAVING HIGH-COMPRESSION RATIO
With a high 7.5 to 1 compression ratio,
Chevrolet's new V8 truck engines squeeze
extra power and work out of every tank
ful of gas. Your ton-mile hauling costs go
down with this modern V8 power on the job!
EXTRA-HIGH POWER PER POUND
The compact Powermatic features of these
advanced V8's result in high power output
per pound of engine weight. More power is
available for hauling.
ADVANCED AIRCRAFT-TYPE VALVES
A completely new valve train design permits
each valve to function independently as in
modern aircraft engines. Valve action is
more positive at all speeds for finer, smooth
er performance.
FLOATING OIL INTAKE . . . FULL-PRESSURE
LUBRICATION
Oil intake selects the cleanest oil for engine
lubrication. Full-pressure lubrication system
provides positive protection for vital engine
parts . . . extends engine life.
V8 standard in the new L.C.F. models, an extra-cost
option in all others except Forward-Control models.
