The 2.0 revision of X-Ray Timer has been approved by Apple and is in the App Store.
This revision added Se-75 as an Isotope selection. I used the values by the manufacturer for the radiation output and the published values for the shielding value of the steel. I don’t actually own any Selenium sources myself, but several people requested this feature.
I decided to go ahead and make this app free for the community. Sales dropped off enough to the point I wouldn’t really get paid anymore so I decided to make it free for everyone. Hopefully now it will be the new standard way work is done. Spread the work around.
I’m working on a Web App version for computer browsers and other smart phones.
Apple just approved Version 2.0 of my Barricade iPhone App!
It should show up in your updates in the App Store on the phone sometime within the next 24 Hours.
I added the ability to change the number of Half-value layers and added Selenium 75 as an isotope selection.
Be sure to watch the App Store for the update.
X-Ray Timer will be updated soon to add Selenium 75 as an isotope.
I hope to develop web app version of them for other smart phones. I may switch all future development to web apps to make it faster and easier to develop.
Apple renamed the iPhone Operating System to iOS4 for the fourth version. This is because it runs the iPhone, iPod, and iPad, not just the iPhone.
I have access to the pre-release version as a developer and am running it on my phone now. Barricade and X-Ray Timer work the same as always so don’t be scared to upgrade.
The update is available to everyone for free June 21’st and I recommend it very much.
One BIG change is that the update is now free for iPod Touch users! I have spoken to iPod Touch users that couldn’t run the apps because they didn’t pay for the OS update. Now it is free so I recommend to do so. (only generation 2 & 3 can run the update)
I tested them both and they are both functional on the iPad.
I’m curious how many techs may get these for use in the field.
NEW for iOS 10. Now at Version 4.0.
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).

When I first uploaded it to iTunes, I accidently put the setting as iPhone only.
I corrected it and now you can install and use the barricade calculator app on your iPod touch now.

** Version 2.1 in App Store Now – Be Sure to Update**
Added ability to to use additional shielding other than the collimator.
This is a very handy utility for Industrial Radiographers.
Ever get tired of using a clumsy slide rule to make radiation calculations? Or, even worse, doing them by hand with a pencil and paper!
This app will eliminate the need for this.
This app is very simple to operate. You simply enter the curies, choose the source, and the shot time in minutes (if less than 60). Hit the Calculate button and your are done.
The app makes four separate calculations for you. I will explain these below;
1) It calculates the the distance to the Barricade (dose of 2 mR/hr) without any shielding factored in.
2) It calculates the distance to the barricade with a common 4 half-value layer collimator included.
3) It calculates the distance to the barricade in an emergency or worse case conditions (eg. source malfunction).
4) It tells you what the maximum allowable reading on the barricade is. This is used when shooting for much less than and hour and the barricade is small enough that more than 2 mR/hr is observed.
Here is a demo video demonstrating the software.
