    Answer:

    The dose is 6 mSV

    Explanation:

    The absorbed dose (in gray – Gy) is the amount of energy that ionizing radiation deposits per unit mass of tissue. That is,

    Absorbed dose = Energy deposited / Mass

    while Dose equivalent (DE) (in Seivert -Sv) is given by

    DE = Absorbed dose × RBE (Relative biological effectiveness)

    First, we will determine the Absorbed dose

    From the question, Energy deposited = 30mJ and Mass = 50kg

    From,

    Absorbed dose = Energy deposited / Mass

    Absorbed dose = 30mJ/50kg

    Absorbed dose = 0.6 mGy

    Now, for the Dose equivalent (DE)

    DE = Absorbed dose × RBE

    From the question, RBE = 10

    Hence,

    DE = 0.6mGy × 10

    DE = 6 mSv
