SUMMARY

The discussion focuses on the conversion between millicuries (mCi) and sieverts (Sv), particularly in the context of internal contamination. It establishes that 1 mCi equals 37 million becquerels (Bq). To convert mCi to Sv, one must consider the radiotoxicity of the specific isotope, which varies significantly, ranging from approximately 1e-8 Sv/Bq for actinides to 1e-12 Sv/Bq for weak beta emitters.

PREREQUISITES
  • Understanding of radioactivity units, specifically millicuries (mCi) and becquerels (Bq).
  • Knowledge of radiation dose concepts, particularly sieverts (Sv).
  • Familiarity with radiotoxicity and its implications in radiation exposure.
  • Basic principles of internal contamination and its health effects.
NEXT STEPS
  • Research the radiotoxicity values for various isotopes used in medical and industrial applications.
  • Learn about the calculation methods for converting Bq to Sv based on isotope-specific radiotoxicity.
  • Explore the health effects of internal contamination from different radioactive materials.
  • Investigate safety protocols for handling radioactive materials in medical and research settings.
USEFUL FOR

Health physicists, radiation safety officers, medical professionals dealing with radioactive materials, and researchers in nuclear science.

hi,
any conversion from mCi to SV and vise versa?

You mean, for internal contamination ?

1 mCi = 37e6 Bq and then you need to use the radiotoxicity of the isotope in question to convert this in an engaged dose. The radiotoxicity is the amount of Sv per Bq, and varies for actinides from something like 1e-8 to 1e-12 or so for weak beta emitters.
