Absorbed dose in A‐150 plastic irradiated by 15‐MeV neutrons was measured using three dosimetric methods: an A‐150 plastic calorimeter, A‐150 ionization chambers, and activation of gold foils. The dose determinations by the calorimeter and ionization chambers agreed to better than 1%, while the activation method yielded a 3.5% lower dose. The agreement between the methods is within the experimental uncertainties.
