SUMMARY

The discussion focuses on calculating the source activity from the dose rate in the MCBEND simulation. The user has measured the dose rate of a gamma source in microSieverts per hour (µSv/h) and knows the distance from the detector to the source. To derive the source activity, one must apply the appropriate formulas that relate dose rate, distance, and source strength, specifically using the principles of radiation physics.

PREREQUISITES

TL;DR: Calculate the Source activity or Source strength from Dose Rate in MCBEND

Hello evryone,
In the MCBEND simulation I've conducted, I have found the dose rate of a gamma source in microSieverts per hour (µSv/h). I also know the distance between the detector and the source. How can I calculate the source activity or strength from this information?
Thank you,
Best wishes
