A typical X-ray uses X-rays with an RBE of 0.850= . If the radiation dosage is 35.0 mrem, find the ene= rgy absorbed by a 72.0-kg patient, assuming one-quarter one quarter of the patient’s body is exposed to X-rays.

 

AD =3D 35.0 x 10-3 rem  

 

AD (rem) =3D AD (rad) x RBE

 

AD (rad) =3D AD (rem) / RBE

 

AD (rad) =3D (35.0 x= 10-3 rem)/0.850 =3D 41.2 x 10-3 rad =3D 41.2 x 10-5 J/kg=

 

E =3D AD(rad) x m =3D (41.2 x 10-5 J/kg)(72.2 kg/4) =3D 741 x 10-5 = J =3D 7.41 x 10-3 J
