What is the equivalent dose limit for a fetus on a monthly basis?

The equivalent dose limit for a fetus on a monthly basis is set at 0.5 mSv. This limit is based on health and safety guidelines to protect the developing fetus from potential radiation exposure, as fetal tissues are more sensitive to radiation during the early stages of development.

The figure of 0.5 mSv considers the cumulative risk of radiation exposure and aims to mitigate any possible adverse effects on fetal development. This threshold is part of the broader radiation protection framework to ensure that radiation exposure to expectant mothers and their developing children is kept as low as reasonably achievable (ALARA principle). By establishing this limit, regulatory agencies strive to balance the benefits of necessary medical treatments with the critical need to safeguard vulnerable populations, such as fetuses, from excessive radiation.
