The article by doctoral researcher Juho Karhu was published in February, 2019, in Optics Letters. The article described a new method for measuring radioactive methane.
"The new method is an optical one based on spectroscopy. Previously, radioactive methane has been measured with accelerator mass spectrometry, involving expensive and huge machines. Optical measuring could be a cheaper and more agile method," Karhu says.
Method - Karhu - Absorption - Materials - Ie
The method created by Karhu is based on the absorption of materials, i.e. how the material retains light at different wavelengths. By measuring how much the material absorbs, we can deduce how much it contains different components.
In his research, Karhu analysed which wavelength the light source used should have in order to measure radioactive methane. This is a first step towards a functioning measurement device.

Optical methods have been used before to measure radioactive carbon dioxide. So far, we have not reached the same precision with optical...
