The analysis was undertaken by means of an HPGe gamma spectrometer. The radiopharceuticals analyzed were: 111In, 201Tl, 177Lu and 99mTc.openAccessconcentration ratiogamma radiationhigh-purity ge detectorsimpuritiesindium 111lutetium 177monte carlo methodquality controlradiopharmaceuticalstechnetium 99thallium 201Gamma-ray impurities of 111In, 201Tl, 177Lu and 99mTc determined by means of a HPGE spectrometerTexto completo de eventohttps://orcid.org/0000-0003-2478-5757https://orcid.org/0000-0001-7733-0153https://orcid.org/0000-0001-8407-9833
