X-irradiation was performed using X-RAD 320 biological irradiator (Precision X-ray, North Branford, CT) operating at 320Kv, 12.5 mA.
At 1 h after injection, these nude mice were irradiated using an X-ray source (X-RAD 320, Precision X-Ray, North Branford, CT, USA), which was operated at 250 kV and 8 mA, with a 2-mm Al filter at a dose rate of 1.2 Gy/min for a total dose of 6 Gy.
The computerized tomography (CT) data were acquired by X-RAD 225Cx (Precision X-ray, North Branford, CT) using 40 kVp X-rays with 2.5 mA current.
To specifically study the effects of lung shielding, we used a Therapax DXT300 X-ray irradiator (Precision X-ray, Inc., North Branford, CT) using 2.0 mm Al Filtration (300 KVp) to irradiate B6 recipients at a dose rate of 2.35 Gy/min.
Rag2 −/− ;Il2rg −/− recipient mice were sublethally irradiated with a dose of 4.2 Gy on the same day with an XRAD320 irradiator (Precision X-ray, Inc, North Branford, Connecticut).
Analysis of a half dozen genes in spotted gar (Lepisosteus oculatus), a large, air-breathing ray-finned North American fish, suggested that its lineage might have diverged from the teleost lineage before the TGD (Hoegg et al. 2004; Crow et al. 2006).
Rays found further north, such as in the Great Australian Bight, tend to be found at depths greater than 80-100 m.
Chandra's image of Jupiter shows strong concentrations of X-rays near the north and south magnetic poles.
A 320 kV X-ray machine (Precision X-Ray INorthNorth Branford, CT, USA) delivered radiation at a dose rate of 2.3 Gy/min.
