Basic Considerations of
Radiation Safety and Barrier Protection
From the ancient Greeks, who initially believed that all matter was made up of atoms,
to the splitting of the atom in the first half of this century, radiation has long
been a source of curiosity for scientists and students alike. This curiosity has
led to many scientific discoveries, leaving us with a nuclear legacy of both risks
and benefits. On November 8, 1895, Wilhelm Röntgen discovered x-rays.
Within one year of his discovery, physicians were using x-rays for diagnosis and
as a new way of gathering evidence to protect themselves against malpractice claims.
X-rays opened the door to a range of new procedures that were considered to be the
most technologically advanced diagnostic tools available. Many believed this new
ability to non-invasively "see inside the body" was miraculous and realized that
x-rays gave great promise to the sick. Thus, the medical world embraced these mysterious
invisible rays with great enthusiasm. However, almost immediately after their discovery,
it became clear that x-rays could cause serious medical problems. Some physicians
received burns that would not heal, requiring amputation of their fingers. Others
developed fatal cancers of the skin, blood, and bone.
Although the information offered in this study guide is fundamental, it is the goal
of this educational program to heighten awareness of radiation safety and the employment
of radiation protection practices.
The information provided in this educational offering is intended to enhance the
understanding of healthcare personnel as it relates to safety and barrier protection
in a radiological situation. Participants should consult their individual institutions,
member organizations, and/or qualified physicians for specific recommendations,
policies, or protocols related to radiological equipment and its use.
