What is the gamma factor for Cs-137 at one meter?

The gamma factor for Cs-137 at one meter is widely accepted to be approximately 0.38 R/(h*Ci). This value is significant as it quantifies the exposure rate, which refers to how much radiation one can expect to be exposed to at a distance of one meter from a source of Cs-137, given a specific activity in curies (Ci).

The gamma factor plays a critical role in radiological safety assessments and is essential for professionals to calculate the radiation exposure levels when working with radioactive sources. This factor allows for the estimation of the dose received by individuals over time based on their distance from the radioactive source and its activity.

Knowing the gamma factor helps in implementing adequate safety measures and ensuring compliance with health regulations when handling radioactive materials, making it a crucial piece of knowledge for those involved in radiographic testing and radiation safety.
