## X-Ray Timer Description
Updated for iOS10.

Only Useful for Industrial Radiographers!

This is an application to replace the aggravating usage of slide rules to calculate radiography shot times.  

It is applicable to Industrial Radiographers working with radioactive materials (not x-ray machines).

It works with both Iridium and Cobalt sources.

This app has been tested in the field with working radiography crews and the response has be great.

Just set the number of curies, the thickness of the steel (inches), and the source to film distance (in inches). Hit the calculate button and you will have the exposure time.

## X-Ray Timer Reviews in United States

### ****- "Question"
Is there anyway you can add a feature where it saves your recent calculations
-- Bigdaddylowk, 2025-11-07

### ***** "Excellent app"
This app is amazing and saves so much time. Would be really cool if there was a memory feature to look up recent calculations while app is still open.
-- Zac Chavez, 2025-03-12

### ***** "Prefer this to the JEM calculator"
This app works great. As long as I enter all the numbers in correctly my film turns out. It even works well when I’m calculating for a concrete shot. It stopped working after a recent IOS update. Hoping it gets back up and running soon!
-- Sling05, 2020-11-11

### ***** "Great"
This app works very well just like using a slide calculator
-- Raistlinsly1, 2017-02-01

### ***-- "Great for Xray Hands"
Simple yet great app for those out there pushing pills. 3 stars because it has some bugs that need fixing now. Updated my phone to iOS 10 and now this app crashes if 2 or more fields have a period in it. Will fix review to 5 stars once bugs are removed.
-- tterb0331, 2016-09-15

### *---- "Way off"
This app has been confusing me. I have this and one other gamma ray app along with the old school exposure calculator that companies give you. Shooting a 42" panoramic, it says I should shoot it 1min 35secs. Which is what I shoot a 36" panoramic with the same cuties. At a 4 minute develop time for the 36", it's perfect density. The other app I have says 2 min 10sec which sounds more accurate. Think I'll be using my other app instead of this one.
-- Jarrett Billiot, 2016-01-22

### ****- "Use it all day.."
Need an update already, like which wire to use, maybe with the coundown it shows the density climbing up and uou can stop it at your desired density...ect. Love the app. Looking forward to see whatsnext
-- Cali_SVT, 2015-06-18

### ***** "Great"
If possible to add for Double/Single wall application
-- NDT Insp, 2014-06-23

### ***** "Works could add sone things"
Add what kind of film double wall single wall pipe density per name
-- Vortex 55, 2014-03-07

### ****- "Great but"
It would be nice to select a film type Instead of looking for the R factor but I use it at least 3-5 times a week
-- h de heiheb, 2013-04-16
