Myocardial perfusion scans performed at 10:00 and 14:00 on Thursday November 3rd, 2016. The KIT1 did help me to visually observe the decay of the approx 850MBq 99mTC-Sestamibi over the time following the procedure. Currently (Sunday 06 November) we near the nominal pre event count levels (half live 6,01 h). As you can see even scary high gamma activity is not all bad. At least for me (and a few hundreds of thousands in the last fifty years) useful to asses heart malfunction conditions. I hope that the sharing of this data from medical diagnostics field will have a impact on the way you perceive nuclear topics and environment issues. There is tons of info about it on the internet.
