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.
To calculate the equivalent dose in millisieverts (mSv) from alpha radiation, you need to apply a radiation weighting factor (WR) specific to alpha particles. The equation to calculate the equivalent dose is:
Equivalent dose (mSv) = absorbed dose (Gy) x WR
Given that the absorbed dose is 51 mrad (millirads) and 1 Gy is equivalent to 100 rad, we can convert the absorbed dose to Gy:
Absorbed dose (Gy) = 51 mrad x (1 Gy / 100 rad) = 0.51 Gy
The radiation weighting factor for alpha particles is 20. Therefore, applying this factor, we find:
Equivalent dose (mSv) = 0.51 Gy x 20 = 10.2 mSv
So, the equivalent dose in millisieverts from absorbing 51 mrad of alpha radiation is 10.2 mSv.
