Is the Na22 nuclear instrument environmentally friendly and reliable?
Thread Content
Are nuclear instruments such as the Na22 nuclear densitometer truly environmentally friendly? I really want to give it a try; those with experience, please share your advice! Thank you! :handshake:handshake:handshake

The decay process does not produce highly radioactive neutrons or gamma rays, and in most cases, a piece of thick paper or a thin layer of metal foil is sufficient to block its radiation. This nuclide is present in trace amounts in sodium and its compounds found in nature, and it is associated with natural background radiation. Sodium-24 is also naturally occurring, but it has a shorter half-life; it undergoes beta decay, with magnesium as its decay product.
Can’t it be measured using other principles? There’s no need to choose it unless it’s necessary
