beta emitter


Also found in: Encyclopedia.

beta emitter

A radioisotope which decays by emitting an electron particle. Beta emitters are labelled as “soft” emitters if the electron is of low energy and has a short penetration distance, or “hard” if it is high-energy and with a great penetrating distance.

The naturally occurring radionuclides210Pb (beta emitter) and 210Po (alpha emitter, decay product of 210Pb) have been detected in bone from caribou sampled in Canada at mean levels of 3800 and 3070 Bq/kg (Macdonald et al., 1996); in Saskatchewan and the Northwest Territories at a range of means of 274 to 531 Bq/kg (210Pb) and 562 to 1022 Bq/kg (210Po) (Thomas et al., 1994); and in Alaskan reindeer bone at approximately 300 Bq/kg (Beasley and Palmer, 1966).
One day, doctors may even be able to select from a family of beta emitters with different energies--and therapeutic ranges--to tailor the radiation's reach to a particular cancer's size.

As part of his studies on irradiated materials, the DMN adopts a measuring gas release aimed to evaluate the kinetics of gas release in increments of temperature maintenance with time measurement the real release samples irradiated beta emitters / gamma can be contaminants.
This isotope has tremendous potential to take up market share of beta emitters and brachytherapy.
The final standards are: combined radium 226/228 of 5 picocuries per liter; a gross alpha standard for all alphas of 15 5 picocuries per liter, not including radon and uranium; and a combined standard of 4 millerems per year for beta emitters. The standard from uranium will be 30 micrograms per liter.
The radioisotopes used on these patients included yttrium-90, rhenium-186, and erbium-169, all of which are beta emitters but which have different penetration distances in soft tissue.

Alpha emitters deposit higher energy over a significantly shorter distance versus beta emitters, providing single-cell kill while leaving normal surrounding tissue unharmed.
This extension consists of a concrete building nuclear processes and for the storage of radioactive nuclear materials: alpha emitters, beta emitters and gamma emitters (mainly tritium).
Segments in the therapeutic market are beta emitters, brachytherapy isotopes, and alpha emitters.
