Phosphorus: Radionuclides

Abstract

32 P and 33 P are important radionuclides of phosphorus with half‐lives of 14.3 and 25.3 days, respectively, and which decay via β − emission. These isotopes (of 23 known) have anthropogenic sources and are prepared by the enrichment of sulfur. The radionuclides are used in tracer studies primarily as phosphate, or other common phosphate forms such as “phosphate rock” or ortho‐phosphoric acid. Various labeling and therapeutic studies have been performed in the fields of biology, botany, and in clinical medicine and are mentioned herein. Radioisotopes of phosphorus can be detected by liquid scintillation counting. There is, however, limited knowledge about remediation as 32 P and 33 P are short‐lived.

Labile Zinc-Assisted Biological Phosphate Chemosensing and Related Molecular Logic Gating Interpretations

“…In the adenosine unit case, ADP can be displaced by 1, N 6 -ethenoadenosine triphosphate (ε-ATP) in the presence of Ca 2+ on actin . However, to the best of our knowledge, there is no work about phosphate–phosphate addition–displacement behavior studied directly by 31 P NMR spectroscopy . In addition to anions, metal cations have innumerable roles and importance in biological processes in the human body and biology at large. − Metal ion homeostasis is also important and considered pertinent in varying degrees to the possible etiology of serious diseases such as Alzheimer’s disease. , Among the ions, the zinc dication (Zn 2+ ) is important because its concentration in the human body affects and controls cellular systemic function, especially in neuronal systems. − Zn 2+ is ubiquitous and essential.…”
