Title: Radiation Safety Orientation for Residents
1Radiation Safety Orientation for Residents
2Why is Radiation used at Rhode Island Hospital?
- Radiation is used for diagnosis, therapy, and
research. - Large quantities are used for patient therapy.
- Smaller quantities are used for diagnostic
procedures and medical research - Special training and monitoring are required in
areas where personnel use radiation.
3Classification of Radiation
- Machine produced when the machine is turned
off, radiation is no longer produced. - Radioactive Materials materials that
continuously produce radiation - no off switch.
4Radiation Labeling
5Types of Radiation use at RIH
- Diagnostic And Therapeutic Radiation Generating
Equipment (RGE) - Radioactive Materials (RAM) - Nuclear Medicine
- Therapeutic RAM Nuclear Medicine And Radiation
Oncology - Research And Analytical Laboratories
6Authorization for RAM
- Radioactive Material can be used only under an
Authorized User - An application must be completed and approved by
the Radiation Safety Committee
7Occupation Radiation Exposure Limits
- Whole body 5,000 mrem/year
- Extremities 50,000 mrem/year
- Eye 15,000 mrem/year
- Fetus 500 mrem/gestation period (declared
pregnancy)
8Dosimetry
- All personnel likely to receive greater than 500
millirem/yr occupational radiation dose are
required by Rhode Island regulations to be
monitored for radiation exposure. - The dosimetry badge program is managed by the
Medical Physics Office. - .
9Dosimetry
- For research or Xray only a whole body is worn at
the trunk level. A ring badge must be used if
extremities are exposed - When lead aprons are used
- For light fluoro users, ONE badge is worn at the
collar - For heavy fluoro users, a badge is worn at the
collar outside the thyroid shield, and one at the
waist INSIDE the lead apron
10Training for Radiation Safety
- Those who use the following equipment or
material need training - X-ray, CT, Fluoroscopes
- Radioactive material in
- Nuclear Medicine
- Research Labs using radioactive material
-
11Who needs credentialing?
- Physicians other than Radiologists doing fluoro
in any area, i.e. - Cardiac Cath Lab
- Electrophysiology Lab
- Endoscopy
- Operating Rooms
12Credentialing Process
- Required for all physicians except for
Radiologists - Training required because of possible burns that
dont appear for 2-4 weeks - Request privileges through Medical Staff Office
- Training provided by Medical Physics Department,
or on-line - Pass Fluoro Exam
13MRI Safety
- MRI machines generate a very strong magnetic
field within and surrounding the machine.This
field is always ONeven when nobody is in the
room. - Metallic fragments or implants in the body can be
dislodged. - Field interferes with the operation of implanted
devices such as pacemakers or medical pumps.
14MRI Safety
The field can cause loose magnetically
susceptible materials even at a distance to be
accelerated into the bore of the magnet with a
force to cause injury to anyone in or around the
MRI unit. Only qualified pre-screened individuals
are permitted to enter this room. Room
Labeling MRI rooms are recognized by signs
saying "CAUTIONSTRONG MAGNETIC FIELD"
15Laser Safety
- Lasers are used mainly in the OR, Dermatology and
Ophthalmology - Lasers can cause eye injuries and skin injuries
- Only trained physicians and nurses can use lasers
16Laser Safety
17Laser Safety
Laser credentialing is required for physicians
through the Medical Staff Office There is a
laser-trained nurse who is responsible for laser
safety in the OR. Eye Protection and Skin
Protection required for staff and patients
