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]

ISO 3696 (Water for analytical laboratory use) specifies a purity of ten parts per billion, or 10×10 −9 ― this water cannot be kept in glass or plastic containers as they leach impurities into the water, and glassware must be washed with hydrofluoric acid before use. Ten parts per billion is equivalent to a homeopathic dilution of 4C.
Global shortages of nuclear chemical needed for cancer scans will see patients’ appointments cancelled, minister warns
Curium hydroxide Cm(OH) 3 is a radioactive compound first discovered in measurable quantities in 1947. It is composed of a single curium atom and three hydroxy groups. It was the first curium compound ever isolated. [3] [4] Curium hydroxide is an anhydrous colorless [2] or light-yellow [5] amorphous gelatinous solid that is insoluble in water. [1]

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.
