Tips & Best Practices
-
Always verify that you select the correct original and target units to ensure accurate conversions
-
Use the tool for precise conversions in regulatory, medical, or scientific contexts where exact factors apply
-
Remember that conversions assume ideal decay rates and do not account for complex decay chains or isotope differences
Limitations
-
Conversion calculations treat radioactive activity as a simple decay rate without considering isotope-specific behavior
-
Does not incorporate decay chain effects or uncertainties related to measurement
-
Obsolete units like Rutherford are included but may not be applicable in all contexts
