"Lutetium drug radiates beta rays
and given the good features and qualities of the drug, it is used to treat different tumors," Kamran Ariana, a faculty member of Mashhad University of Medical Sciences, said on Monday.
It is mostly shell model calculations that are carried out for the angular and energy distributions of the two beta rays
for medium heavy nuclei.
These devices monitor and measures ionizing radiations such as X-rays, Beta rays
, Gamma rays.
Therefore they are more penetrating than other types of radiation such as alpha and beta rays
(Kova'cs and Keresztes 2002).There are several usages of nuclear techniques in agriculture.
Strontium-90, materials that emit beta rays
and causes bone cancer, likewise hit 1.2 million becquerels, JIJI said, citing TEPCO.
Tepco said the level of those that emit beta rays
was 230 million becquerels per liter.( ANI )
About 10 tons of water may have leaked, the utility said, noting the pipe contained some 37 million becquerels per liter of radioactive substances that emit beta rays
such as strontium-90 in a reading in August, against the legal limit of 30 becquerels for strontium-90.
"We are investigating the cause." Tepco said the radiation measured was beta rays
, which would be easier to protect against than gamma rays.
