 Context examples 

Upon intra-arterial hepatic administration of holmium 166 microspheres, this agent is able to emit both beta particles direct killing cells and gamma photons for nuclear imaging.

(Holmium Ho 166 Poly(L-Lactic Acid) Microspheres, NCI Thesaurus)

Iodine-131 primarily emits beta particles and has a half-life of 8 days.

(Iodinated I-131 Serum Albumin, NCI Thesaurus)

I-124 MoAb A33 delivers beta particle emitting I-124 nuclide directly to metastatic colorectal tissues, thereby this agent could be used in kinetics studies or radioimmunotherapy.

Radiation of beta particles during radioactive decay.

(Beta Radiation, NCI Thesaurus)

This radionuclide has a relatively long half-life, 30 years, and decays by emitting beta particles.

(Cesium Cs 137, NCI Thesaurus)

(Carbon C-14, NCI Thesaurus)

A Beta Radiation Effect involves biological damage caused by beta particles emitted from a radioactive source.

(Beta Radiation Effect, NCI Thesaurus)

Emitted by phosphorus P32, beta particles directly damage cellular DNA and, by ionizing intracellular water to produce several types of cytotoxic free radicals and superoxides, indirectly damage intracellular biological macromolecules, resulting in tumor cell death.

(Phosphorus P-32, NCI Thesaurus)

This radioimmunoconjugate binds to tumor cells that express the extracellular domain of prostate-specific membrane antigen, delivering beta particle radiation selectively to tumor cells expressing this antigen and so limiting the exposure of normal tissues to ionizing radiation.

(Lutetium Lu 177 Monoclonal Antibody J591, NCI Thesaurus)

Beta particle energy causes breakage of chemical bonds and ion formation in molecules, such as DNA and RNA, resulting in cell death or damage.
