Yes & no. Radium is radioactive, but not terribly much so; it has a half-life of 1622 years. The average human being receives about 100 mR/year, and wearing a watch with radium in it 24/7/365 will give you an additional dose of about .008 mR/hr (70 mR/yr).
The nuclear regulatory commission has determined that Anything under 200 mR/yr is harmless, and the maximum safe annual dose is 500 mR/yr. Anything above that is considered unsafe. Bear in mind that these are extremely cautious guidelines.
The bad rep with Radium came from the "Radium Girls", which became a fantastically famous court case. These women painted radium on watch and clock dials & hands from roughly 1917-1940. They suffered severe radiation effects because of the manner in which they were painting on the radium.... they would put the brushes in their mouths to moisten them & sharpen the tips.... thereby ingesting large quantities of radium over the course of their career.
It isn't clear how well known the dangers of radium were in 1917 but no warning was given to these poor ladies.

Yes, radium paint used in compasses is dangerous because radium is a radioactive material that can emit harmful radiation. Prolonged exposure or ingestion of radium can lead to serious health issues, including an increased risk of cancer. It is important to handle radium-containing compasses with care and follow proper safety protocols.

What are some things that are made of radium?
Radium is used in luminous paint, radiation therapy, and some specialized medical devices. It was historically used in clock and watch dials for luminosity, though this practice has largely been discontinued due to its radioactive properties.
Is radium dangerous or explosive?
Yes. Radium is a highly radioactive alkali earth metal, and inhalation, injection, ingestion or body exposure to radium can cause chemical burns, radiation burns and can lead to cancer and other disorders. Radium is chemically similar to calcium, and it has the ability to replace calcuim in bones, which is extremely harmful. A link is provided to the Wikipedia article on radium.

What dangerous gas is produced when radium decays?
Radon
Do glowsticks have radium in them?
No, glowsticks do not contain radium. Glowsticks work by a chemical reaction that produces light through chemiluminescence, typically utilizing a mixture of hydrogen peroxide and a phenyl oxalate ester. Radium is a radioactive element that is not used in glowsticks for safety reasons.
What is the mass number of the radium isotope used in paint?
The mass number of the radium isotope used in paint is typically 226. Radium-226 is commonly used in luminescent paints due to its ability to emit a glow after exposure to light.
Is radium spring dangerous because of radium?
Yes, radium springs can be dangerous due to its radioactive properties. Exposure to radium can increase the risk of various health issues such as cancer and other radiation-related illnesses. It is important to limit exposure to radium-infused water sources and follow recommended safety precautions.
