However, delays prevent the sample from being tested until 7.6 days have passed. Measurements indicate the presence of 6.5 micrograms of radon-222. WebObjectives Germanium-68 has a half life of 270 days and decays to gallium-68 with a half life of 1.13 hours which makes the two isotopes ideal for a medical isotope generator. The short half life of gallium-68 allows preparation, purification and imaging of small molecules and peptides and the generator can be eluted multiple times in a day for patient imaging. coffee makers that use cone shaped filters https://liverhappylife.com
