Sentence examples for radioactivity source from inspiring English sources

The methodology involves the listing approach and the IE screening and grouping methodologies and the focus was on internal IEs due to random failures of components and human errors with full power operational conditions and the reactor core was the radioactivity source.

This could be done with accuracy and reproducibility tests, to be performed using suitable calibrated radioactivity sources.

To evaluate plant and soil attenuation of radioactivity, we performed transmission scans, in which each of the detectors in the PET scanner ring measured the radioactivity transmitted through the sample (i.e., the plant) from known radioactive source rods (Ge).

Brachytherapy dates back to 1901 (shortly after the discovery of radioactivity by Henri Becquerel in 1896) when Pierre Curie suggested to Henri-Alexandre Danlos that a radioactive source could be inserted into a tumour.

In the classical application to radioactivity by Currie [ 60], the presence of a radiation source is tested against the null hypothesis that no source is present in excess of the background radiation.

Radiation sources of a known amount of radioactivity were imaged and reconstructed using the same scanning protocol above.

The amount of source radioactivity was 0.3 MBq at the time of the comparison of PET scanners.

The radioactivity of this source was calibrated with a Germanium-semiconductor spectrometer at an accredited calibration center (Japanese Radioisotope Association, Tokyo, Japan); the level of uncertainty in the measurement was <1.5%% (k = 2).

Source-half depth distance (SHD) was initially calculated to obtain a constant dose rate of 0.5 Gy min−1 and monthly adapted from the Co source radioactivity decrease.

Pre- and post-injection counts were subsequently acquired by recording the radioactivity of the source using the Toshiba-GCA gamma camera, calibrated on 140 KeV.

The source-half-depth distance was initially calculated to obtain a constant dose rate of 0.5 Gy/min, and was adapted monthly to the cobalt-60 source radioactivity decay.
