Yttrium (Z=39) is not an essential element, but is used clinically for cancer treatment as the radionuclide 90 Y, half-life 2.7 days, a pure β-emitter . It can be delivered to cells as a strongly chelated complex, e.g. (90 Y-DOTA-Phe-Tyr)octreotide (SMT487, DOTATOC), figure 11, targeted to somatostatin receptors (SSTRs).
Humans are exposed to heavy metals every day because these elements are used in various industrial processes from which many modern conveniences are derived. For example: • Arsenic is found in wood preservatives, insecticides, pesticides, and poisons. • Iron is found in vitamin supplements. •
10 Νοε 2023 · The alpha-emitter radium-223 (223 Ra) is presently used in nuclear medicine for the palliative treatment of bone metastases from castration-resistant prostate cancer. This application arises from its advantageous decay properties and its intrinsic ability to accumulate in regions of high bone turnover when injected as a simple chloride salt.
19 Φεβ 2024 · Uses of Curium. Curium is mostly utilized for scientific research. Because it does not occur naturally in the earth’s crust, the radioactive element has only been employed in fundamental research studies due to limited laboratory production. Furthermore, it does not react with other chemicals.
Curare is used for centuries by humans, and its toxic patho-mechanism [1] has been meticulously examined. This insidious neurotoxin has killed many humans and animals over the centuries. At first, curare was known as “arrow poison”.
Curium has two main uses: as a fuel for Radioisotope Thermal Generators (RTGs) on board satellites, deep space probes, planetary surface rovers and in heart pacemakers, and as a alpha emitter for alpha particle X-Ray spectrometry, again particularly in space applications.
17 Απρ 2019 · Cu was also used as alloying element to adjust the degradation rate. Thus, the role of Cu in the alloy design will be very important for the development of new alloy.
