Science Warns Public on Safety Limit
Of Medical, Dental X-Ray Radiation
Washington (U.R Science
warned the American public to
day that it is using up about one
third of its atomic radiation
safety limit in medical and den-
tal X-rays.
The findings of leading U.S.
scientists indicated there is no
such thing as a "safe" amount
of atomic radiation.
The medical profession was
called upon to reduce X-rays to
the lowest frequency of use con
sistent with medical necessity.
"Keep the dose as low as you
can . . . the potential danger is
great," the scientists warned.
That advice comes from lead
ing U.S. scfentists who partici
pated in a year-long study spon
sored by the National Academy
of Sciences of "biological effects
of atomic radiation.
Her To Stay
But their "initial report," pub
. lished today, recognizes that
atomic energy is here to stay.
It recognizes that if the world
escapes nuclear war, with its
threat of possible extinction of
the race, it is headed irrever
sibly into an era of mushroom
ing atomic power.
So man must learn to live
with and control radioactivity of
his own making. Balancing the
great prospective benefits against
the known dangers, the scien
tists came up with some propos
als they believe will give hu
manity full scope ot exploit its
new energy source and at the
same time survive its hazards
and prosper.
Dangerous Practices
As of now medical and dental
X-ravs are piling up more
troubles for generations yet un
born than are either nuclear
weapons tests or nuclear power
plants. Genetic scientists par
ticularly deplored use of X-rays
for fitting shoes and taking pic
tures of yet to be born children.
They said such applications were
dangerous and medically inde
fensible.
But the prospective future of
atomic power, with iU vast ac
e u m u 1 a tions of radioactive
waste, make it urgently neces
sary for this generation to put
control measures into effect
now.
Any addition, however small.
to the natural background of
radiation causes genetic changes
which can inflict tragic injury
on children born generations
hence. . That is because man's
inheritance mechanism is by far
the most susceptible of all his
organs to radiation harm.
So what the scientists ,are con
cerned with is not simply the
fate of the people and Institu
tions and governments of this
century or even the next. They
are concerned with the long
range fate of Homo Sapiens.
They recommend:
Recommend Limits
1. That population as a whole
be limited to an average radia
tion dose on the reproductive
glands, over and above natural
radiation, of 10 roentgens from
conception to aze 30. A roentgen
is a unit of radiation. An aver
age dental X-ray delivers five
roentgen of stray radiation to
his sex glands. The maximum
total 30-year dose for any indi
vidual would be 50 roentgens.
2. To assure that this average
dose and the permissible maxi
mum are not exceeded, ."records
should be kept of the total ac
cumulated lifetime exposure to
radiation of every person. And
medical application of X-rays
should be rigidly limited to a
minimum "consistent with medi
cal necessity." It was empha
sized this would not rule out
tuberculosis checkups or other
cases in which the "benefit out
weighed the cost."
The scientists did not suggest
that the 10-roentgen limit would
be "safe." From a genetic stand
point there is no safe limit. But
they said it would be "reason
able" in an age committed to
development of atomic energy.
They seemed more concerned
with X-rays than with weapons
tests, which to date have had
only a "negligible" effect upon
mankind. .
Robeson Contempt
Citation Affirmed
Washington flj.R) The
House Un-American Activities
committee today affirmed by a
7-0 vote a subcommittee recom
mendation that Negro Singer
Paul Robeson be cited for con
tempt of Congress.
Th committee also voted un
animously to recommend a con
tempt citation for Clark Fore
man of New York.
Testimony by Leonard Bou-
din, also of New York, was re
ferred td the Justice Department
for possible perjury prosecution.
The committee referred action
on a subcommittee's further rec
ommendation that Prof. Otto Na
than, executor of the late Al
bert Einstein estate, also be cit
ed for contempt.
All four men testified Tues
day at subcommittee hearings on
issuance of passports to alleged
Communists and their sympath
izers. Conviction for perjury or
contempt carries a maximum
penalty of a year's imprisonment
of a year and a $1000 fine on
each count.
. New Trick in Silo
Domes Introduced
Marietta, O. (U.RO A new
trick in silo domes has been in
troduced by the Marietta Con
crete corporation.
To top its new concrete farm
siols, the firm created a plastic
roof. The new top. called 'silo
lite, is constructed of fiberglass
reinforced plastic.
While it is translucent, the
dome shows" great strength and
can be installed easily on exist
ing wooden or metal silos.

Ike Probably Must Tell People
Again About Physical Fitness
By LYLE C. WILSON
United Press Correspondent
Washington (U.R) President
Eisenhower probably must tell
the American people again
whether he
feels fit and
ready to cam
paign for a
second term.
But, this time it
may be differ
ently staged.
An off-the-
cuff response
to a news con
ference ques
tion seems now to be the likely
manner in which Mr. Eisen
hower will let the people know
what is in his mind. He will be
asked about his political plans
the next time he faces a news
conference.
An elaborate television report
on his own well being was ar
ranged last February for the
President to reveal that he felt
sufficiently recovered from a
heart attack to take on four
more White House years.
Often Bench Victims
Heart attacks are killers.
When they do not kill they often
bench their victims. The most
enthusiastic Ike-men were will
ing back there in the autumn of
1955 to believe that Mr. Eisen
hower was lost to the Republi
can Party. The popular belief
also was that Mr. Eisenhower
could not run again.
A full dress response to that
widespread doubt was essential
and it was made by the Presi
dent in his television appearance
of Feb. 29. Surgery is something
else again. A successful opera
tion may leave the patient as
strong or even physically in
better condition than before. Mr.
Eisenhower's attending doctors
evidently consider their work to
have been succesful and that
the President will gain physi
cally rather than lose by reason
of it.
A more informal assurance of
his willingness to run again is.
therefore, indicated assuming,
of course, that Mr. Eisenhower's
excellent recovery continues.
Just when the President next
will submit himself to news
questions is not known. Harvard

.STRICKEN President Eisenhower is shown enjoying
himself at the annual White House Press Photographers'
dinner at the Sheraton-Park Hotel in Washington the
evening before he suffered an attack of ileitis (inflamma
tion of the lower portion of the small intestine). The
President's physician ordered him taken to Walter Reed
Hospital as a precautionary measure.
Medical School Professor David
D. Rutstein said Tuesday in
Cambridge that the forecast six
week period of recovery from
surgery w-as the absolute mini
mum and too optimistic. Might
take two or three months, Dr.
Rutstein said.
Would Raise Doubts
A three-month convalescence
from successful abdominal sur
gery surely would raise some
serious doubts about the Presi
dent's comeback powers and per
haps, about his fitness for an
other term. His attending phy
sicians are top flight men, how
ever, and they are committed to
the President's recovery in terms
of weeks instead of months. Time
will tell about that.
Republican leaders and Mr.
Eisenhower's White House asso
ciates are as confident in private
as in public that the President
will run again. They do not be
lieve that a successful bout with
the surgeons will lessen his vote
appeal. They argue that his
physical reaction to the ordeal
of surgery will be the best pos
sible campaign proof that the
Eisenhower heart is ticking on
schedule.
