Understanding Neutron Radiography Reading V-Kodak Part 2 of 3

Selection Of Films For Industrial Radiography
Industrial radiography now has many widely diverse applications. There are
many considerations in obtaining the best radiographic results, for example:
• the composition, shape, and size of the part being examined--and, in some
cases, its weight and location as well
• the type of radiation used--whether x-rays from an x-ray machine or
gamma rays from a radioactive material
• the kilo-voltages available with the x-ray equipment • the intensity of the
gamma radiation
• the kind of information sought--whether it is simply an overall inspection or
the critical examination of some especially important portion, characteristic,
or feature
• the resulting relative emphasis on definition, contrast, density, and the time
required for proper exposure
All of these considerations are important in the determination of the most
effective combination of radiographic technique and x-ray film.
