Question

Repeat problem 2 for a mouse-sized cylindrical mass of water 3 cm in diameter by 3 cm long.

This is problem 2:

Answers should be these:

137 A glo source is homogeneously distributed throughout a right cylindrical bucket of water having diameter - height - 30 cm. What is the approximate absorbed dose rate in Gy per day in water at the center of the bucket if 160 atoms of 15jCs disintegrate per g s? Use the straight-ahead approximation and the 137 mean-radius method of calculating the photon dose. Give the answers for each component of the dose.

Explanation / Answer

If the density of Cs-137 is the same, the dose rates will also remain the same. This is because the dose rate is given in Gy/day. Gy stands for gray which is defined as the no. of joules of radiation energy per kilogram of matter.
