Study Notes
Radiation Safety
- Equivalent dose for a radiation worker who received 25 mGy from X-rays is calculated by multiplying the absorbed dose (25 mGy) by the radiation weighting factor (WR) for X-rays, which is 1, resulting in an equivalent dose of 25 mSv.
Absorbed Dose
- The total absorbed dose to the liver is calculated by dividing the energy absorbed (0.015 joules) by the mass of the liver (0.9 kilograms), resulting in an absorbed dose of 0.0167 Gy (or 16.7 mGy).
Radiation Safety Principles
- ALARA stands for "As Low As Reasonably Achievable," a principle in radiation safety that aims to minimize radiation exposure to individuals.
Radiation Units
- The unit for expressing equivalent dose is Sievert (Sv), often expressed in millisieverts (mSv) or microsieverts (μSv).
Radiation Weighting Factors
- The radiation weighting factor (WR) for X-rays is 1, used to calculate the equivalent dose from an absorbed dose.
