Radiation Conversion Formulas
Gray to Rad:
rad = Gy × 100
Calculation: 1 Gy = 1 × 100 = 100 rad
Sievert to Rem:
rem = Sv × 100
Calculation: 1 Sv = 1 × 100 = 100 rem
Roentgen to Gray:
Gy = R × 0.00876
Calculation: 100 R = 100 × 0.00876 = 0.876 Gy
Milligray to Gray:
Gy = mGy ÷ 1000
Calculation: 1000 mGy = 1000 ÷ 1000 = 1 Gy
Microsievert to Sievert:
Sv = μSv ÷ 1,000,000
Calculation: 1000 μSv = 1000 ÷ 1,000,000 = 0.001 Sv
Millirem to Rem:
rem = mrem ÷ 1000
Calculation: 1000 mrem = 1000 ÷ 1000 = 1 rem

Daily Uses of Radiation Measurements
Chest X-rays deliver about 0.1 mSv radiation dose for medical diagnosis
Nuclear workers have annual exposure limits of 20 mSv for safety
CT scans typically expose patients to 2-10 mSv depending on body part
Radiotherapy delivers 50-70 Gy in fractions to treat cancer tumors
Background radiation exposure averages 2-3 mSv per year naturally
