### Let's test the units above whether they are equivalent or not?

Joule = 6.24150934 * 10^12 # MeV
GBqh = (10**9) * 3600 # Bq s

u1 = 0.93337 # MeV / (Bq s)

u2 = 0.5385 # Gy kg / (GBq h)

u2MeVBqs = u2 * Joule /  GBqh

# Bozunum başına ortalama yayılan enerji
# Average energy released in beta decay $^{90}$Y

print u2,"Gy kg / (GBq h) = " ,u2MeVBqs, " MeV / (Bq s)"

0.538500000000000 Gy kg / (GBq h) = 0.933625772108333 MeV / (Bq s)

# Conclusion:

MeV / (Bq s): average energy released (Dose) in a decay (or energy released (Dose) per decay)
