RADIATION PROTECTION PROCEDURES

1
RADIATION PROTECTION PROCEDURES

• Patient

2
COMMUNICATION

• Reduce radiation exposure

3
PREPARATION

• Explan-ation
• View
• Position

4
POSITIONING

• Correct quality film
• Incorrect repeat film

5
GONADAL SHIELDING

• Radiation damage
• Shields Shadow Contact

6
GONADAL SHIELD GUIDE

• Child-bearing age
• Child
• Area view not needed
• Pregnant

7
RADIATION PROTECTION PROCEDURES

• Health Care Worker

8
3 MAJOR PRINCIPLES

• Time
• Distance
• Shielding

9
TIME exposure proportional to time

• Leave room or use stand behind shield
• Reduce retakes
• Use fast exposure time

10
DISTANCE radiation varies inversely as the
square of the distance

• Farther away, fewer rays
• 2 x distance 4 x protection

• Stand at right angle to radiation source

11
SHIELDING absorption reduces energy

• Lead lined rooms and windows
• Lead lined aprons, gloves, and gonad shields.

12
RADIATION DETECTION

• Film badges
• Thermoluminescent dosimeters
• Pocket ionizing chamber
• Geiger-Mueller detector
• Victoreen condenser R-meter
