What does joule per milligram represent in radiation dosimetry?

Joule per milligram expresses the energy absorbed by a material of one milligram, representing the absorbed dose at a small mass scale.

Why convert joule per milligram to femtogray?

Converting to femtograys allows expressing absorbed doses in extremely small units suitable for measuring microscopic or single-event radiation effects.

Are the units joule per milligram and femtogray related to the gray unit?

Yes, both units relate to the gray, which is the SI unit of absorbed dose equal to one joule per kilogram. 1 J/mg equals 1 million grays, and 1 fGy equals 10^-15 grays.

In which fields is this unit conversion commonly used?

This conversion is common in radiobiology research, radiation chemistry, microfabrication, sterilization dose assessments, microdosimetry, detector calibration, and space radiation analysis.
