Thus, the two largest radiations of the family 85% of the genera and 94% of the species belong to these two sister clades, which diverged from the remaining legume lineages shortly after the origin of the family [10], [39].
These were once a large radiation but have been largely replaced by the Actinopterygii, the class of ray-finned fishes.
The hospital's medical physicist, who was apparently accustomed to calibrating larger radiation beams, did not realize that smaller beams needed to be handled differently, radiation experts say.
At a given temperature T, there is then not enough thermal energy available to create and emit many large radiation quanta hν.
Even for people exposed to large radiation doses, like the 80,000 to 90,000 survivors of the atomic bombs exploded over Hiroshima and Nagasaki, it has been hard to find excess cancers.
The report also describes the panic within the Kan administration at the prospect of large radiation releases from the more than 10,000 spent fuel rods that were stored in relatively unprotected pools near the damaged reactors.
Dr. Einstein said that when tech 99 was not available, doctors could use substitutes, but that these gave the patient larger radiation doses or provided poorer image quality to the doctor.
