Question

What are some ways in which technologists can reduce x-ray exposure to their patients? what are some ways in which technologists can reduce their exposure to radiation while imagining patients?
(Radiologic question)

Answer 1

A) 1) the amount of time and the intensity at which the xray wil give analytical images must be optimized and a minimum exposure time must be maintained to avoid excss radiation exposure

2) shielding of the unexposed region can be done by using lead material containing coats, throid collars

3) avoid duplication of Xrays

4)use of the faster speed film for X-rays. It costs about the same as the conventional D speed film and offers similar benefits with a lower radiation dose. Using digital imaging detectors instead of film further reduces radiation dose.

B) 1) the technologist must be shielded with 0.25mm lead equivalent coat if he has to be nearer to the patient during X ray exposure

2) during the exposure of X rays the technologist can utilize shilding many waays are available :

• Walls, windows, control booths, and doors
• Mobile rigid shields on wheels for transport to various areas
• Ceiling-suspended transparent barriers
• Flexible (lead or lead equivalent) aprons, vests, and skirts
• Thyroid collars/shields
• Lead Gloves
• Leaded safety eye glasses with side shields

The fluoroscopy systems should have two separate shielding screens to protect the operator, and both should be used correctly. A 0.5 mm lead screen absorbs .90% of the scattered radiation.
