Abstract	Background radiation attributed to X-ray and gamma ray emission induced in the spacecraft surrounding the detector and within the detector itself was measured in sample packages of metals selected for their cross sections for specific neutron and proton energies and germanium and thallium-activated sodium iodide (NaI(T1)). Analysis of the spectra for noise and resolution characteristics, nondestructive tests and chemical analysis of the metal foil disks after splashdown, and direct and indirect measurement of the induced radionuclides are discussed. Results of internal and external monitoring of the NaI crystal activation spectrum are compared to that of the Apollo 17 crystal.
