The three ways to reduce radiation dose are time, distance, and shielding. Dose builds with exposure time but falls with the square of distance — doubling your distance quarters the dose. Effective dose in millisieverts lets you compare any exposure to everyday references like a chest X-ray or the annual background dose. Educational estimate only.

Governing equation

D = \frac{Γ A}{r ^{2}} t = \frac{8.4 \times 1 0 ^{- 5} \cdot 37}{1 ^{2}} \cdot 1 = 0.003 mSv

Reading this result: At 1 m for 1 h the estimated dose is 0.003 mSv — about 31 banana-equivalents, a low everyday-scale exposure.
