Dutch version

Dose/ Equivalent dose

Dose : energy absorbed per kg  absorbing material

 

D  = Eabs/m        

 

D     dose in Gy  or  J.kg-1 

Eabs  energy absorbed in J

m    mass  in kg

 

The effect of the ionizing radiation depends  among others on radiation type

This is represented   by the quality factor Q.

Q  for α-radiation is 20 and for  β-radiation is 1.

 

H = Q . Eabs/m                  

 

H    equivalent dose in Sv of J.kg-1

Q    quality factor (no dimension)
