Final answer:
The International Commission on Radiological Protection (ICRP) Publication 103 and the World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) Second Expert Report are the two reports that include guidelines on radiation weight factors (Wr) and tissue weighting factors (Wt) used in radiation dosimetry.
Step-by-step explanation:
Two reports published that provided guidelines on radiation weights (Wr) and tissue weighting factors (Wt) are essential for understanding radiation dosimetry, which plays a critical role in both diagnostic radiology and radiation therapy. The International Commission on Radiological Protection (ICRP) often releases recommendations for these guidelines, and two key documents that include such guidelines are ICRP Publication 103 and the World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) Second Expert Report.
ICRP Publication 103 provides an updated framework for radiation protection, including the latest radiation weight factors and tissue weighting factors. These factors are used to calculate the effective dose of radiation to various tissues and organs, accounting for the varying sensitivity of tissues to radiation damage.
The WCRF/AICR report, on the other hand, offers recommendations for cancer prevention, potentially including guidelines or usage of dosimetric measures in research or clinical settings to minimize the risk associated with radiation exposure.
