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.
