doses and exposure guidelines

Doses and exposure guidelines define safe limits for how much of a substance, like a chemical or radiation, people can be exposed to without significant health risks. A dose is the amount of the substance someone receives, while exposure guidelines set maximum levels considered safe for specific periods, such as daily or annually. These guidelines are based on scientific research and help protect public health by ensuring exposure remains within limits that minimize the chance of adverse effects. They are used by health authorities to regulate environments and ensure safety for everyone.
