In the past several decades, advances in imaging and interventional techniques have been accompanied by an increase in
medical radiation dose to the public. Radiation exposure is even more important in children, who are more sensitive to
radiation and have a longer lifespan during which effects may manifest. To address radiation safety in pediatric computed
tomography, in 2008 the Alliance for Radiation Safety in Pediatric Imaging launched an international social marketing
campaign entitled Image Gently. This article describes the next phase of the Image Gently campaign, entitled Step Lightly,
which focuses on radiation safety in pediatric interventional radiology.

CHILDREN AND RADIATION
SAFETY
IN March 2009, the National Council on
Radiation Protection and Measurement
released a critical report (1) indicating
that radiation dose exposure to the
United States population had increased
dramatically since the early 1980s. This
report disclosed that US citizens had ex-
perienced a sevenfold increase in radia-
tion dose, with computed tomography
(CT) scans and nuclear medicine being
the two largest contributors to medical
radiation. Fluoroscopy used during in-
terventional procedures is the third larg-
est contributor of medical radiation to
the public in the United States, account-
ing for 14% of the medical radiation
dose (1). Although children undergo
medical imaging and intervention in
smaller numbers than adults, they are
more sensitive to radiation effects and
have a longer lifespan during which to
manifest possible changes as a result of
radiation exposure. In addition, some
children who undergo interventional
procedures may have chronic illnesses
and receive a higher lifetime cumulative
dose as a result of repeat procedures
and exposure (2– 6).
There is controversy among medical
physicists and medical experts as to
whether lower doses of medical radia-
tion cause cancer (7–9). However, ex-
trapolation from atomic bomb data, us-
ing the linear no-threshold model,
suggests that even low doses have led to
a small but increased incidence of can-
cer within that study population (10). It
therefore behooves the medical commu-
nity to act responsibly and conserva-
tively by promoting radiation protection
for children and health care workers
during fluoroscopy. The purpose of this
communication is to inform the inter-
ventional radiology community of sim-
ple strategies that may be readily imple-
mented locally to decrease radiation
dose during interventional radiology
procedures. The Image Gently Step
Lightly campaign is a grassroots effort
of the Alliance for Radiation Safety in
Pediatric Imaging and is supported by
its partner, the Society of Interventional
Radiology (SIR). By using the educa-
tional tools provided on the Web site
(www.imagegently.com), interventional
radiologists can minimize radiation
dose to themselves, their medical col-
leagues in the interventional radiology
suite, and most importantly, their pedi-
atric patients.
IMAGE GENTLY
In 2006, spurred by the tremendous
growth in CT scanning and increasing
medical and public concern about radi-
ation dose in children, a small group of
health care professionals started the Al-
liance for Radiation Safety in Pediatric
Imaging. The founding members of the
Alliance were the Society for Pediatric
Radiology (SPR), the American Associ-
ation of Physicists in Medicine, the
American College of Radiology, and the
American Society of Radiologic Tech-
nologists. In 2008, the Alliance, working
entirely through volunteer efforts,
launched the national education/
