CRAY SUPERCOMPUTER WILL SUPPORT CITY OF HOPE 
RESEARCH ON CELLULAR PHONE HEALTH RISK

EAGAN, Minn., July 25, 1995 -- Cray Research, Inc. (NYSE:CYR)
announced today that City of Hope National Medical Center,
Duarte, Calif., installed a Cray supercomputer for research
related to the potential health risks of cellular phone use. 
Terms were not disclosed. 

City of Hope officials said the supercomputer, installed in
second quarter, will be used for engineering research to
quantify human exposure to cellular telephone radiofrequency
waves.  The medical center has been awarded more than $1.5
million from the Wireless Technology Research (WTR) Limited
Liability Company to conduct this research, which is being led
by principal investigator C.K. Chou, Ph.D., director of Radiation
Research at City of Hope.  The research will serve as the
foundation for future biological studies expected to help
clarify whether there are health risks involved with using a
portable cellular phone.  

This is Cray's second order from a hospital.  Earlier this year,
Cray Research also installed a compact supercomputer at
Georgetown Medical Center's Department of Radiology, where it
is being used to run sophisticated new software for improved
breast cancer detection.  By May 1996 Georgetown's Cray
system will enter general use at the hospital and all
mammography patients will be diagnosed with the use of the
supercomputer. 
 
Cray Research provides the leading high-performance
computing tools and services to help solve customers' most
challenging problems.
