The gamma factor of Tm-170 is how much at one meter?

The gamma factor, also known as the exposure rate constant, provides a measure of the exposure rate at a specific distance from a radionuclide, in this case, Tm-170. The value of the gamma factor reflects how much radiation is emitted from a source, allowing for the calculation of radiation exposure for people or equipment nearby.

For Tm-170, the gamma factor is approximately 0.0062 R/(h*Ci) at a distance of one meter. This value is essential in radiographic testing as it helps determine safe exposure levels and informs proper safety protocols when working with radioactive materials. The units indicate that for each curie of Tm-170, the radiation exposure would be 0.0062 roentgen per hour at one meter away from the source.

Understanding the gamma factor is crucial for professionals in radiographic testing as it assists in risk assessment and ensuring adequate safety measures in environments where radioactive materials are handled.
