X-Ray Timer for Android

Android App Store Link

 

Now available on Android!  This has been by far my most popular app on iPhone and now it is available for Android also.

This app was modeled after the slide rules that Industrial Radiographers use to estimate their exposure times.

The app has the ability to change between inches and MM, Curies or TBq. It also obviously has a selector for which isotope you are using.

Barricade for Android

Android APP STORE LINK

 

An Industrial Radiography Barricade Calculator for double checking your barricade or Restricted Area.

The app calculates four numbers that can be handy when performing radiography. The distance with your collimator and shielding, the distance without them (in case the open end of the collimator is unavoidably pointing towards a barricade, the emergency distance (worse case scenario of no shielding and 2 mR/hr), and also the maximum allowable survey meter reading at the barricade when performing compliance verifications.

The dose rate reading is rounded off at 0.1 precision level so don’t push the readings to the limit. More room is better.

The distances are ALL rounded up to the next whole number if they are not a whole number. For example, 50.001 feet will display as 51 feet. And decimal point whatsoever will cause the answer to be rounded up to the next whole number.

I only have the input for time in Minutes. There is a reason for it. If you have such a short time of exposure that the total amount of all exposures is less than 1 minute, you can afford to round up. The distances will be really short. If you are shooting 5 minutes and 30 seconds I would recommend putting at least 6 minutes in you calculations, if not 7, or 8, or 10.

The same goes with curies. It wouldn’t hurt to over estimate your curies. Complying with the regulations by having a little more barricade than needed is better than having too little.

These calculations are your responsibility and this is just made for you to double check yourself. No responsibility for compliance is accepted.

Ug Calculator for Android

This is an Android version of my iPhone app Ug Calc.

It is only useful for Industrial Radiographers.  It calculates the Geometric Unsharpness (Ug)  of a radiograph.  Geometric Unsharpness is also referred to sometimes as Penumbral Shadow.

The app is straight forward.  You just enter the source side of the object to film distance, the source side of object to source distance, and the diagonal size of the source and hit enter.

The app does not collet any data or talk to the internet.

The link to the app is below.

Barricade Version 2.2 in App Store

I have updated my Barricade app to Version 2.2 and it was approved by Apple and is now live in the App Store.

The update was just focused on being recompiled in 64-bit in latest version of X-Code so it could keep working in iOS 11.
