How technetium tc-99m labeled carbon is dosed
From the FDA label for Technegas Kit (application NDA022335). Other technetium tc-99m labeled carbon products — different forms, different strengths — are dosed differently. Follow the label for the one you were prescribed.
For adult patients, the recommended activity of sodium pertechnetate Tc 99m injection to be loaded in the Technegas Crucible is 400 MBq to 1,000 MBq (10.8 mCi to 27 mCi) to achieve a lung count rate between 1,500 counts per second (cps) and 2,500 cps at the end of the last respiration. (2.2) For pediatric patients aged 6 years and older, a sufficient amount of Technegas Aerosol should be inhaled to achieve between 500 cps and 1,000 cps at the end of last respiration. The radioactivity to be loaded in the Technegas Crucible is a fraction of the recommended activity for adults adjusted by body weight. (2.2) Administer as soon as possible following preparation and complete inhalation within 10 minutes of preparation. (2.2) For drug handling, breathing techniques, preparation, and dosimetry information, see the full prescribing information.

The safety of Technegas Aerosol was evaluated in 291 patients undergoing ventilation studies with prospective data collection. Patients received an amount of Technegas Aerosol to achieve 1,500 cps to 2,500 cps by oral inhalation. The mean age of patients was 60 years (range:18 to 95 years); distribution by race was 92 % White, 7% Black or African American, 0.3 % Asian, and 0.3 % unreported; and distribution by ethnicity was 4% Hispanic/Latino and 96 % non-Hispanic/Latino. Adverse reactions were reported in 10 patients (3.4%). The adverse reaction occurring at ≥ 1% in patients receiving Technegas Aerosol was hypoxia (1%). Adverse reactions reported at < 1% were dizziness, dysgeusia, cough, dyspnea…
