Lesson 2.7

Question 1

Walls adjacent to radiographic rooms
should be shielded with lead (1.6 mm
thick) extending all the way to the ceiling to prevent radiation leakage.

Answer 1

Lead Shielding

Question 2

Darkroom personnel should not be exposed to radiation. The processing area must be located away from the exposure room to reduce exposure risks.

Answer 2

Protecting Darkroom Staff

Question 3

Unprocessed X-ray films are highly
sensitive to radiation, so proper shielding prevents fogging or
degradation of image quality

Answer 3

Protecting Film Material

Question 4

Maintaining a safe working environment in the darkroom ensures staff safety and prevents accidents related to electricity, fire hazards, chemical exposure, and ventilation issues.

Answer 4

Health and Safety in the Processing Area

Question 5

what are the Electrical Safety:

Answer 5

-equipment placement -grounding (earthing) of appliances
-avoid trailing cables
-use pull-cord switching

Question 6

Electrical equipment should be kept away from sinks and manual processing units to prevent electrical hazards.

Answer 6

Equipment Placement

Question 7

All electrical devices must be properly grounded to avoid electric shocks.

Answer 7

Grounding (Earthing) of Appliances

Question 8

Loose wires or trailing cables should be secured properly to prevent tripping hazards

Answer 8

Avoid Trailing Cables

Question 9

Light switches should be pull-cord operated to reduce the risk of electric shock, especially in wet areas.

Answer 9

Use Pull-Cord Switching

Question 10
