Recommendations to reduce Radiation Exposure
The main objective of radiation protection procedures in an X-Ray Diagnostic Installation is to
limit the Radiation Exposure arising from the use of the Diagnostic Equipment as low as possible
so that the radiation doses received by the radiological personnel and general public never
exceeds the maximum permissible dose limits recommended by ICRP (International
Commission on Radiation Protection).
a) The radiation exposure to the patient should be the minimum exposure required to
produce images of good diagnostic quality. Use radiation with care, caution and at a rate
which is ALARA - ‘As Low As Reasonably Achievable’
b) The speed of the film, or screen and film combinations should be of fastest speed
consistent with the diagnostic objective of the radiographic examination.
c) When a patient or film must be provided with auxiliary support during radiation
exposure:
(i)
Mechanical holding devices shall be used when the technique permits.

For Your Safety
(ii)
Individuals may be permitted to hold the patient when absolutely necessary
and no individual shall be used routinely for this purpose to the exclusion of
others who might share the task.
(iii)
If a human holder is required, the holder shall be positioned such that no part
of body shall be struck by primary X-Ray beam unless protected by at least
0.5 mm lead equivalent and shall be protected from direct scatter radiation by
protective lead apron of not less then 0.25 mm lead equivalent.
d) Gonadal shielding of not less then 0.25 mm lead equivalent shall be used for patients who
have not passed their reproductive age during radiographic procedures in which gonads
are under primary beam, except, in cases where shielding would interfere with diagnostic
procedures.
e) Doors of the Room/OT where X-ray equipment is installed should be closed before
making exposures.
f) The X-ray beam should not be directed towards doors or windows of the room, or
towards control panel or darkroom walls unless no other geometry is possible.
g) Obey radiation protection rules pertaining to time, distance and shielding.
h) Prefer low exposure settings to high.
i) Use Collimator to set minimal useful field size; keep Image Intensifier in close proximity
to the patient.

First Aid In Case of Electrical Shock
1. Switch OFF the Power Supply: If this is not possible, protect yourself
with dry insulating material and pull the victim clear off the conductor.
Do not touch the victim with your bare hands until he/she is clear off the
conductor.
2. Place the victim in supine position.
3. Keep the air passage clear by turning the head to one side, opening the
patient’s mouth and cleaning it of water, saline, mucus or blood, a lot of
which might have accumulated in the back of the throat.
4. If the jaw is rigid, try to force the mouth open by pressure on the gum
behind the last molar tooth of the lower jaw. When the upper air passage
is cleared, tilt the head backward and force the jaw forward from the
angles of the jaw in front of the ears. This would prevent mechanical
obstructions to the upper air passages.
5. Hold the chin up and forward with one hand and pinch the nostril of the
victim with other.
6. Take a very deep breath and apply your mouth to that of victim and
blow into his mouth until the chest of the victim moves up indicating
filling of the lungs (Never allow the chin to sag).
7. When the chest has moved up, withdraw your mouth and allow the chest
to sink back.
Have someone else sent for a Doctor.
Keep patient warm and loosen his/her clothing.
Do not give liquids until the patient is conscious.

2. X-RAY/LBD SWITCH
This is a toggle type switch. It has two positions. When positioned in LIGHT side, light
bulb of LBD glows so that area of X-Ray exposure can be adjusted through light beam.
When switch is in this position, X-Ray exposure cannot be started. On the X-RAY side, it
enables X-Ray exposure.
Note: During position of light beam, mains indicator turns OFF but voltmeter
continues to show input voltage.
3. VOLTMETER
This voltmeter indicates input supply to equipment circuits. Red band is provided on
voltmeter at 230 V. Voltage compensator switch is adjusted until pointer on voltmeter is at
this red band.
4. mA METER
This meter indicates X-Ray tube current (mA) during exposure. The Needle deflects during
exposure & indicates tube current as per setting on Technic/KVP selector switch.
NOTE: For exposure less than 1.0 sec. duration, pointer may not get enough time to
travel up to the desired position e.g. for an exposure of 30mA, 0.50 sec, mA
meter pointer will not reach up to 30mA mark.
5. MAINS ON INDICATOR
