Curium is not currently used as nuclear fuel due to its low availability and high price. [43] 245 Cm and 247 Cm have very small critical mass and so could be used in tactical nuclear weapons, but none are known to have been made. Curium-243 is not suitable for such, due to its short half-life and strong α emission, which would cause excessive ...
Sulfides, selenides and tellurides of curium have been obtained by treating curium with gaseous sulfur, selenium or tellurium in vacuum at elevated temperature. [17] [18] Curium pnictides of the type CmX are known for nitrogen, phosphorus, arsenic and antimony. [11]
Curium metal is a radionuclide and emits alpha particles upon radioactive decay. [12] Although it has a half life of 34 ms, many curium oxides, including curium sesquioxide, have half lives nearing thousands of years. [7] Curium, in the form of curium sesquioxide, can be inhaled into the body, causing many biological defects.

Global shortages of nuclear chemical needed for cancer scans will see patients’ appointments cancelled, minister warns
Curium hydroxide is an anhydrous colorless [2] or light-yellow [5] amorphous gelatinous solid that is insoluble in water. [ 1 ] Due to self-irradiation, the crystal structure of 244 Cm(OH) 3 decomposes [ clarification needed ] within one day ( 244 Cm has a half-life of 18.11 years); for 241 Am(OH) 3 the same process takes 4 to 6 months ( 241 Am ...
He managed to secure patents for both elements. His patent on curium never proved commercially viable because of the element's short half-life, but americium is commonly used in household smoke detectors and thus provided a good source of royalty income to Seaborg in later
