Barricade 2.1 in App Store

Barricade calculator app has been updated to version 2.1 in the App Store.

It’s product page with app store link may be found in the following link;

This version adds the ability to add shielding in addition to the collimator.  This can be added in inches rather than in the half-value layers.  The default colimator is still added in half-value layers.

Other improvements include faster performance and retina graphics for the iPhone.

Code 313

Code 313 Users Manual

Code 313 is a calculator for interpreting industrial radiographs in accordance with ASME B31.3.

Please read this description and watch the video below (Coming soon) before purchasing to decide if this is the app for you.

The app caculates the most common discontinuities such as cracks, incomplete penetration, internal porosity, slag inclusions, and undercutting.

It also calculates IQI (penetrameter) sizes.  It has three sections, welds with no reinforcement, and welds reinforced on one or both sides.

NOTE: The calculations for welds with reinforcement are based on the MAXIMUM allowable reinforcement.  The code references the “ESTIMATED” reinforcement, so use the numbers in the app with this in mind and as just references.

This app DOES NOT replace the code itself nor the need to have the code.  There are many other issues in the code that need to be referenced, this is just a calculator.  One common example is you need the porosity ccomparison charts from the code for reference and need to be able to reference the rules and conditions.

Use this app at your own risk.  No guarantee is made.  recommended use is as a second opinion to your own interpretation.

X-Ray Timer Version 2.0 in App Store – And it’s free!

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.

Barricade Updated to Version 2.0

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.

iPhone Apps Working in iOS4

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)

Barricade Calculator App

** 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.

This is an PDF article I wrote to help people understand how to print directly to a PDF file from their computer.

It is to help understand the process to prevent people printing a document to paper, then scanning it.
