Processing And Developing Flashcards
What do X-ray photons do to the silver halide crystals that cover a film
Sensitise them
Why should X-ray solutions be kept covered
To reduce oxidisation
How many steps are the for manual film processing and what are they
5 Develop Wash Fix Wash Dry
If a film packet is placed backwards in the mouth what happens
The foil is visible on the radiograph
During digital radiographs X-ray energy is released as light and converted into what
Electrical signals
Why does digital radiography require less radiation than traditional X-rays
The uses lower wave length radiation
What happens if incorrect angulation occurs for a bitewing
Contact points appear overlapped

Non infectious waste
In manual processing the temperature of the developer should be what
20 degrees
The presence of crystals on a radiograph is due to what
Insufficient washing after fixing
How would a spillage of developing chemicals be cleared up
By absorption in inert materials and disposed of in a container for collection
Developer solution works on which crystals
