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 most popular and useful levels are included in this applicaton:

• Cage: Inside the RAD+ placed on the bottom of the chamber, used for small animal whole body irradiation
• Shelf Level 5: The highest practical shelf level that still offers reasonable size for Petri dishes, well plates, falcon tubes etc., used for High Dose Cell or targeted tumor irradiation
• Shelf Level 3: Provides the largest field size allowed with the RAD+ still in place, used for cell or targeted tumor irradiation

INSTRUCTIONS:

1. Upon first entry, you will be taken to the calibration screen.
2. Once there, enter the centerlane dosage rate for each particular level. This information is available on your RS 2000 dose map sheet that was left with the unit at installation. This only has to be done once, or after the unit has been recalibrated. Hint: After entering the value, touch anywhere outside the keyboard to commit that value.
3. After the calibration values have been entered, go back to the main screen by touching the "Location" back button.
4. Choose the location you wish to calculate the dosage for.
5. The resulting table will provide the set time to use for typical Accumulated Dose results
