Radiation Protection Flashcards
Provide quality diagnostic images and therapeutic radiation to patients.
general aim of a radiologic technologist
Emergency, Surgery, Oncology are known examples of the medical field
that need the radiologic technology profession for diagnosis and
treatment.

why do we need to protect ourselves from radiation
Radiation effects can either produce a random or certain effect,
therefore radiation interaction must be as low as reasonably achievable.
This applies to all medical workers and patients.
cardinal principles of radiation protection
minimized time
apply shielding
maximum distance
(MAM)
exposed to radiation as fast as possible
minimized time
apply shielding in between the source and to the subject
apply shielding
be far from the source as energy decreases when it travels through space
maximum distance
for patients, the shorter time to be exposed, the lower radiation to be transmitted/absorbed
time
for medical professionals, as much as possible, avoid being exposed unless necessary but brief.
time
this protection is useful mostly for patients who move involuntarily and have multiple procedures
time
materials
shield
lead is useful for wearable protective equipment. concrete is useful for walls

doing for unnecessary exposure to sensitive organs for both patients and professionals
shield
useful mostly for procedures involving prolonged exposure for both patients and professionals
shield
as energy travels farther, its strength decreases.
distance
importance
doing for unnecessary exposure to people who don’t need a radiation exposure
distance
useful mostly for relatives and professionals who don’t need to be exposed
distance
patient facing the image
receptor (film
patient facing the x-ray
tube (Source)
application of alara
avoid repat of exposure as much as possible
use optimal exposure factors
in certain cases, the exposure time is reduced
proper instructions, communications, and understanding are vital
if not needed, radiation must be shielded or distant
