RS 2000 Dosage Calculator

Welcome to your new RAD SOURCE RS 2000 irradiator time calculator.

This application will assist in calculating the set time to achieve a total or accumulated dose at various dose rates or shelf levels.

As a user, you know that there are 6 possible shelf levels plus the bottom cage position inside the black RAD+ reflective chamber. The Inverse Square Law dictates that the closer to the x-ray emitter (top of chamber), the higher the dose rate; the trade-off to higher dose rates is smaller field size.

The four most popular and useful levels are included in this application:

Animal Cage: inside the RAD+ placed on the bottom of the chamber

Level 3: provides the largest field size allowed with the RAD+ still in place

Level 4: a good compromise between the higher dosage of shelf level 5 and the larger field size of shelf level 3

Level 5: the highest practical shelf level that still offers reasonable size for Petri dishes, well plates, falcon tubes etc.
