Density for Android

Android App Store Link

Android version of my Density variation calculator.

It is a simple app that calculates allowable density variation under the rules of ASME Section V.

You measure the density in the body of a hole type IQI or next to the essential wire of a wire type IQI and then it calculates the min and max densities in the area of interest.  The ranges are minus 15% to plus 30% ( except the plus 30% can be exceeded when using a shim under a hole type IQI).

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.

X-Ray Timer Version 4 in App Store

Version 4 is live in the app store which fixes the crashing issue in iOS 10.

If the old version is still on your phone it should auto-update.

If you had deleted it you will have to download the latest version.

Density App removed from App Store Temporarily

I was informed by a user that my Density app wasn’t working.  I confirmed that it would just crash on my phone and refused to run.

I’m not sure what would have caused this to occur but not affect my other apps but I am looking into it.

I pulled it from the app store so new users would not download it in the meantime.

X-Ray Timer Version 3 in App Store

X-Ray Timer has been updated to Version 3.0 and is available in the app store.

The product page for the app with app store link can be found at the link below;

http://www.lancehenderson.com/x-ray-timer-app/

This version adds the ability to use SI units in addition to standard US units of measure.

Other improvements include visual and performance improvements, and retina graphics for the iPhone.

This version requires iOS 5.

Density App

 

 

***Pulled from App Store pending investigation of crashing***

Density Variation Calculator for ASME Section V.

This is a small app that calculates the allowable density variations in ASME Section V.

The code allows a minus 15 or plus 30 variation and this app does those calculations for you while taking into account the max and min allowable densities and if shims are utilized.

The app is free in iTunes or in the iPhone app store.  It is compatible with the iPhone, iPod Touch, and iPad.

 

 

It is not an app you will need to use daily but I hope you enjoy the app.

Ug Calc

In The App Store!

Ug Calc is a simple Geometric Unsharpness calculator for Industrial Radiography.

All you have to do is plug in the distance from the Object (source side of the object or weld) to the film and to the source distances, along with the source size (diagonal).

This is not a difficult calculation to make but using this app makes it simpler and no need to keep looking up formulas.

NOTE:  The source side of the object or weld on double wall exposure welds with Single Wall viewing is the inside surface of the pipe near the film.  Basically the wall thickness (and maybe reinforcement).

On other welds it is more obvious where the source side of the object or weld is.

Click on the image below to enlarge.

Example problem: What is the Ug when the weld to film distance is 0.5 inches and the weld to source distance is 8 inches with a source size of 0.180 inches?

Answer: 0.011 inches of Ug.   (Ug = (0.5 x 0.180)/8)

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 App

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).

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.
