Actinium-225 is part of the 4n +1 chain (the neptunium series). Actinium-225 has a half-life of 10 days and decays by alpha emission. It is part of the neptunium series, for it arises as a decay product of neptunium-237 and its daughters such as uranium-233 and thorium-229. It is the last nuclide in the chain with a half-life over a day until ...
Radium-223 (223 Ra, Ra-223) is an isotope of radium with an 11.4-day half-life. It was discovered in 1905 by T. Godlewski, [ 2 ][ 3 ][ 4 ] a Polish chemist from Kraków, and was historically known as actinium X (AcX). [ 5 ][ 6 ] Radium-223 dichloride is an alpha particle-emitting radiotherapy drug that mimics calcium and forms complexes with ...
This is made by the alpha decay of actinium-225. The generation of one short-lived isotope from longer lived isotope is a useful method of providing a portable supply of a short-lived isotope. This is similar to the generation of technetium-99m by a technetium generator. The actinium-225 is made by the irradiation of radium-226 with a cyclotron ...
The actinide series is a group of chemical elements with atomic numbers ranging from 89 to 102, [note 1] including notable elements such as uranium and plutonium.The nuclides (or isotopes) thorium-232, uranium-235, and uranium-238 occur primordially, while trace quantities of actinium, protactinium, neptunium, and plutonium exist as a result of radioactive decay and (in the case of neptunium ...
The national emergency number for ambulances in South Africa is 10 177. These publicly operated services are supplemented by multiple private-for-profit ambulance companies, NetCare 911 [3] and ER24, [4] of which operate locally and nationally. The statutory services and private companies are further supplemented by voluntary ambulance services ...
South African sangomas have been long and vocal advocates of a local traditional plant called unwele or kankerbos (Sutherlandia frutescens) claiming it assists in the treatment of HIV/AIDS, cancer and tuberculosis. [45] A review of preclinical data on Sutherlandia frutescens show no toxity and justify controlled clinical studies. [46]
Minister of Health v New Clicks. New Clicks South Africa (Pty) Ltd v Tshabalala-Msimang and Another NNO; Pharmaceutical Society of South Africa and Others v Tshabalala-Msimang and Another NNO 2005 (2) SA 530 (C) is an important case in South African administrative law. However, note that this case went on appeal, first to the Supreme Court of ...
Koeberg Nuclear Power Station South Africa is the only country in Africa with a commercial nuclear power plant. Two reactors located at the Koeberg nuclear power station account for around 5% of South Africa's electricity production. Spent fuel is disposed of at Vaalputs Radioactive Waste Disposal Facility in the Northern Cape. The SAFARI-1 tank in pool research reactor is located at the ...
