Suppose a person absorbed 51 mrad of alpha radiation What would be the equivalent dose in millisieverts?

Express the biological damage in millisieverts to two significant figures.

To calculate the equivalent dose in millisieverts (mSv) from the absorbed dose in millirad (mrad), we need to multiply the absorbed dose by a radiation weighting factor (WR).

For alpha radiation, the radiation weighting factor is 20. Therefore, the equivalent dose in millisieverts (mSv) can be calculated as follows:

Equivalent dose (mSv) = absorbed dose (mrad) x WR

Equivalent dose (mSv) = 51 mrad x 20

Equivalent dose (mSv) = 1020 mSv

Therefore, the equivalent dose in millisieverts (mSv) from absorbing 51 mrad of alpha radiation is 1020 mSv to two significant figures.
