What's new in v1.12

Description

From the listing uploaded by “appupdater”.

The program is developed to calculate the exposure time for radiographic inspection using industrial source of ionizing radiation Iridium-192. To calculate the exposure time set: - The current activity in Ci - Radiation thickness in mm; - Focal length in mm. And also select the type of film, blackening density and controlled material. Current activity is calculated automatically if source data is entered: initial activity and estimated date of receipt. You can specify no more than five sources in the program. Knowing the half-life of the Iridium-192 isotope, which is 74.4 days, the current activity is calculated. Using known data about the controlled object (standard size, category of welded joint), it is possible to calculate the focal length, as well as the number of controlled areas. If you find any errors or have any suggestions for further development of the program, write to me by email. Exposure time calculations are experimental and may not meet your specifications.
