What key information should a label on radioactive materials provide?

The label on radioactive materials serves a crucial role in ensuring safety and compliance with regulatory guidelines. It should provide information that is essential for the handling and storage of these materials. The type of radiation indicates the kind of potential hazards associated with the material, such as alpha, beta, or gamma radiation, which informs personnel of the necessary protective measures needed to safely work with or near the source.

The activity level is a quantitative measure of the radioactivity of the material, typically expressed in units such as curies or becquerels. This information is critical for understanding the intensity of radiation and assessing the potential exposure risks.

Additionally, appropriate safety precautions must be mentioned on the label. These precautions guide users on how to minimize exposure and handle the materials safely, ensuring that workers implement the correct protective measures, such as the use of personal protective equipment (PPE) or specific containment methods.

While the other options may contain useful information, they do not focus on the immediate requirements or hazards associated with handling radioactive materials. For instance, the manufacturer name and expiration date may be relevant for ensuring quality control but do not address safety directly. Similarly, storage location and date of purchase could help in inventory management but are less critical in terms of immediate safety. Color coding and supplier
