What happens to radiation intensity as you move from a distance of 152.4 cm to 1524 cm from the source?

As the distance from a radiation source increases, the intensity of radiation decreases significantly due to the inverse square law, which states that the intensity of radiation is inversely proportional to the square of the distance from the source.

When you move from a distance of 152.4 cm to 1524 cm, you are increasing the distance by a factor of 10. According to the inverse square law, if the distance from the source increases by a factor of 'd', the intensity decreases by a factor of 'd^2'. In this case, since the distance has increased by a factor of 10, the intensity will decrease by a factor of 10², or 100. Thus, the overall effect is a significant decrease in intensity.

This principle is fundamental in radiation safety and radiographic testing, as it underscores the importance of distance in minimizing exposure to radiation. Understanding this concept aids in effectively managing radiation hazards in various applications, including testing and inspection procedures.
