SUMMARY

The conversion of MeV/cm3 to rads is not feasible due to dimensional discrepancies. MeV/cm3 measures absorbed radiation per volume, while rads (and its SI equivalent, Gray) measure absorbed radiation per mass. To convert MeV/cm3 to Gray, one must multiply by the density of the material in kg/m3, as Gray is defined as J/kg. Therefore, the correct relationship involves density to bridge the units.

PREREQUISITES
  • Understanding of radiation units, specifically rads and Grays.
  • Knowledge of dimensional analysis in physics.
  • Familiarity with energy density concepts, particularly MeV/cm3.
  • Basic principles of mass and volume relationships in physics.
NEXT STEPS
  • Research the relationship between energy density and mass density in radiation physics.
  • Study the conversion factors between rads and Grays, including practical applications.
  • Explore dimensional analysis techniques for unit conversions in physics.
  • Investigate the implications of radiation measurement in different materials and contexts.
USEFUL FOR

Students in physics or engineering, researchers in radiation measurement, and professionals working with radiation safety and dosimetry.

Homework Statement



Convert MeV/cm^3 to rads

Homework Equations


I wish I knew..


The Attempt at a Solution



I tried looking up the unit conversions, but find nothing that connects them, I know rads is connected to the Gray which is J/Kg but can't connect it to the MeV/cm^3. Any ideas?

Hi ~Sam~! :smile:

rad is the old cgs unit, gray (small "g") or Gy (= 100 rad) is the SI unit … see http://en.wikipedia.org/wiki/Gray_(unit)"

MeV/cm3 has the wrong dimensions, so you can't convert it to rad or Gy …

MeV/cm3 would convert to Gy times density (J/kg times kg/m3) :wink:

Gy measures absorbed radiation per mass, MeV/cm3 measures absorbed radiation per volume
