Which of the following statements about radioactive powder exposure is true?

To support the answer indicating that statements 1 and 2 are true while statement 3 is false, it’s important to understand the general principles surrounding radioactive powder exposure.

If both statement 1 and statement 2 address typical effects or safety protocols related to radioactive powder exposure—such as the potential health risks associated with inhalation or direct contact, and the necessity for proper protective equipment to prevent contamination—then affirming these as true aligns with established safety guidelines in the handling of radioactive materials. Health risks from radioactive powders include radiation exposure that can cause cellular damage or increase the risk of cancer, emphasizing the significance of knowing how to mitigate these risks through appropriate safety measures.

Statement 3 being false suggests that it might provide incorrect information about the nature of radioactive materials or their effects, which would further corroborate the validity of statements 1 and 2. Overall, recognizing the truth in the first two statements while identifying a flaw in the third reflects a comprehensive understanding of the protocols necessary for safe exposure to hazardous materials, particularly those that are radioactive.
