What is radium used for today?

Answer 1

Self-luminous paints (only in the past, before 1930), Ra-Be neutron sources, preparation of radon from RaCl2 solutions, medical uses for the treatment of conditions such as cancer (now being replaced by radioactive cobalt, 60Co sources, 137Cs, etc.).

Its use in medicine has declined because of its cost, and its use in consumer goods (to illuminate watch and clock hands and numbers, as well as instrument dials) was halted because it can cause radiation injury. It is still used for some radiography and as a source of neutrons.

Answer 2

Today radium has only limited applications in research laboratories, for example for the preparation of radon standard solutions, in neutron sources of the type Ra-Be, etc.

Possible use in radiotherapy of some cancers.

Radium was used in the past for luminescent painting of watches and other instruments, was used in toothpaste, cosmetics, etc. These applications are not permitted now because radium is strongly radioactive and dangerous.

Answer 3

Radium is no longer widely used due to its radioactivity and associated health risks. In the past, it was used in luminescent paints, self-luminous aircraft instruments, and some medical treatments. Today, safer alternatives are used for these applications.

Answer 4

Self-luminous paints, neutron sources, medical uses for the treatment of conditions such as cancer (now being replaced by radioactive cobalt, 60Co sources), cancer therapy.

Answer 5

People use Radium in chemistry, and people now use it in hospitals.
