International Cohort Study on Mobile Phone
Users (COSMOS)
The COSMOS study aims to conduct long-term 
health monitoring of a large group of people to 
determine if there are any health issues linked to 
long-term exposure to radio frequency energy 
from cell phone use. The COSMOS study will 
follow approximately 300,000 adult cell phone 
users in Europe for 20 to 30 years. Additional 
information about the COSMOS study can be

Risk of Brain Cancer from Exposure to Radio
Frequency Fields in Childhood and
Adolescence (MOBI-KIDS)
MOBI-KIDS is an international study investigating 
the relationship between exposure to radio 
frequency energy from communication 
technologies including cell phones and brain 
cancer in young people. This is an international 
multi-center study involving 14 European and 
non-European countries. Additional information 
about MOBI-KIDS can be found at

Surveillance, Epidemiology, and End
Results (SEER) Program of the National
Cancer Institute
The National Cancer Institute (NCI) actively 
follows cancer statistics in the United States to 
detect any change in rates of new cases for 
brain cancer. If cell phones play a role in risk for 
brain cancer, rates should go up, because heavy 
cell phone use has been common for quite some 
time in the U.S. Between 1987 and 2005, the 
overall age-adjusted incidence of brain cancer 
did not increase. Additional information about 
SEER can be found at

Cell Phone Industry Actions
Although the existing scientific data do not justify 
FDA regulatory actions, the FDA has urged the 
cell phone industry to take a number of steps, 
including the following: 
• Support-needed research on possible
biological effects of RF for the type of signal
emitted by cell phones;
• Design cell phones in a way that minimizes
any RF exposure to the user; and
• Cooperate in providing users of cell phones
with the current information on cell phone use
and human health concerns.
The FDA also is working with voluntary 
standard-setting bodies such as the Institute of 
Electrical and Electronics Engineers (IEEE), the
