A nuclear medicine technologist received an absorbed dose of 1.8 milligrays (mGy). Assume that 1.0 mGy came from beta radiation (Wr = 1), and the remainder came from alpha particles (Wr = 20). What is their equivalent dose?

Equivalent dose reflects that different kinds of radiation affect tissue differently, so we weight each absorbed dose by its radiation weighting factor and add them up: H_T = sum(D_T,i × w_Ri).

Here, the total absorbed dose is 1.8 mGy. The beta portion contributes 1.0 mGy with a weighting factor of 1, giving 1.0 mSv. The remaining 0.8 mGy comes from alpha particles, with a weighting factor of 20, contributing 0.8 × 20 = 16 mSv. Adding these together yields 1.0 + 16 = 17 mSv.

So the total equivalent dose is 17.0 millisieverts.
