What is the gamma factor of Ir-192 at one meter?

The gamma factor of Iridium-192 (Ir-192) is a crucial value used in radiography and radiation protection to quantify the radiation exposure rate at a specific distance from a radioactive source. For Ir-192, the established gamma factor at one meter from the source is approximately 0.59 R/(h*Ci).

This value represents the dose of radiation (in roentgens per hour) that would be received from one curie of Ir-192 at a distance of one meter. The gamma factor is essential for professionals in the field to ensure that proper safety measures and exposure limits are adhered to when working near this isotope, as it is a common source used in industrial radiography.

Understanding this factor allows radiographers to calculate how much radiation they may be exposed to and aids in planning the necessary protective equipment and procedures to minimize risk.
