Gamma Ray Calculator

Adjust R factor and buildup for your processor or temperature and its bang on for everything. I shoot my way out of every situation with this app! The most used and useful app on my phone.

I use this app on a daily basis and it works great if you use the R Factor Chart that it comes with and keep your chemicals at around 72 degrees Fahrenheit. You'll never have to second guess yourself.

Please include also exposure time for aluminum...i really need it...im working in aluminum shipbuilding..hope to hear from you soon

App is great. Why you didn't use the real brands for R factors. Example, kodak MX125 or AA400. As you know there is a very fine grain film type of M for kodak as well. By the way app is perfect, I really trust it.

It helps the NDT inspector like me...

Verry usefull

Good app accurate for most part.

Very very usefull

Thank you ❤❤❤

Nice app

Nice tool

Very easy to calculate pipe thicknes/ expossure time.

Use it every day; works well; formulas all correct, very accurate

Application is to good but cardinar distance should also be provided

Very good application

Great app. Have to adjust R factors a bit but it is always in the ballpark.

Very nice. ...

Have had this app for 2 yrs. It's great. Needs a distance calc. Built in. Would recommend

I been using this app for 2 years now it's an awesome app. Sure there are some parts that need fixing (R factor) but that's based on what I was taught. Each person is different and are taught different ways. So can't complain I put in my own info and it never fails simple and easy

I use this app daily, the right R factor takes a little time to find but my shots consistently dense 2.9-3.2

I find its most accurate around 73-76 Degrees. No calculator is going to be perfect. But this will get you in the ball park.

Exposure calculators are so helpful when you work on pipelines......it so usefull to any ndt tech especially bombers.

Great calc...shot times are spot on...times match up identical to sentinel plastic slip stick...for future update, please add 2.5" in pipe schedules

Great app. Would love it even more if it would automatically copy source strength from decay calculation to exposure calculator
