The detection of ionised oxygen indicates that many very brilliant stars, several dozen times more massive than the Sun, have formed in the galaxy and are emitting the intense ultraviolet light needed to ionise the oxygen atoms.
They then carried out high-sensitivity observations with ALMA [3] and found light from ionised oxygen in SXDF-NB1006-2, making this the most distant unambiguous detection of oxygen ever obtained [4].
Despite the Atomic Energy ( Radiation Protection) Rules, 2004, making mandatory the registration of X- ray, CT scan and other diagnostic tools using ionised radiation for medical, industrial or other purposes, the panel found a dismal scenario.
Washington, Feb 14 (ANI): After reporting excess calcium as an indicator of prostate cancer, researchers at Wake Forest University School of Medicine and the University of Wisconsin have now identified an even more accurate biomarker of the life-threatening disease-high levels of ionised serum calcium.
