Have you ever had a fracture and needed to get an X-ray? You might not have known it at the time, but the process whereby an image was taken of your skeleton is called radiography – it is defined as an imaging technique used in order to view the internal form of an object, another example of which you’ll find in an airport checking bags at the security line. What do you know about the study?

Personnel should wait for a few minutes before entering the exposure area
Personnel should wear a lead-lined apron before entering-the exposure area
Personnel should enter the exposure area without fear of radiation exposure
Personnel should take a reading with a survey meter before entering the exposure area.

May have a cumulative effect which must be considered when monitoring for maximum permissible dose
Will be beneficial since they build up an immunity to radiation poisoning
Will have no effect on human beings
Will have only a short-t€rm effect on human tissues
1.5 to 15 R
25 to 70 R
200 to 800 R
All of the above doses would most likely be fatal
Directly by personnel equipped with special protective clothing with speciar protective clothing.
By remote handling equipment
Directly by personnel with special protective clothing except when radiographs are being made
By the same methods used for low intensity emitters
The radiograph will not show proper contrast
It will be impossible to fix the radiograph permanently
There will be a general "fogging" condition over the entire radiograph
There will be a tendency for each area of the film to affect the development of the areas immediately below it
The thickness of the part
The material of the specimen
The voltage range of the available X-ray machine
All three of the above factors
A dark, intermittent or continuous line
A light, irregular line
Either a dark or light line

Intensifies the scatter radiation more than the primary radiation
Decreases the contrast of the radiographic image
Intensifies the primary radiation more than the scatter radiation
Should not be used when gamma rays are emitted by the source of radiation
