Examples of Roentgen in a sentence
For example, a measured entrance exposure of 0.50 Roentgen from a Mo/Mo Target Filter system at 30 kVp with a measured HVL of 0.36-mm aluminum yields an average glandu- lar dose of (0.50 R) × (174 mrad/R) = 87 mrad or 0.87 mGy.*Wu X.
One Roentgen is equal to 2.58 x 10-4 Coulomb per kilogram of air.
A measurement of the biological effects resulting from ionizing radiant energy where Roentgen is the amount of radiation leading to the absorption of 88 ergs of energy per gram of air.
