Brightest Gamma Ray Ever!

A new gamma ray has been created. It is more than a thousand times brighter than the sun!!! Thats very bright. Physicists have discovered that ultra-short duration laser pulses can interact with ionised gas to give off beams that are so intense they can pass through 20 cm of lead and would take 1.5 m of concrete to be completely absorbed. The ray has plenty of helpful uses for the medical field, mainly for xrays. Radiotherapy and radioisotope production for PET (positron emission tomography) scanning. It also has the ability to monitor the intesity of nuclear waste. the laser pulses are short enough, lasting a quadrillionth of a second, to capture the response of a nucleus to stimuli, making the rays ideal for use in lab-based study of the nucleus.
