The compass itself is not radioactive, the part that is radioactive is the backing. Compasses with glow-in-the-dark backings that aren't connected to electricity are laced with small amounts of radioactive material to make them glow. Radioactive compasses are typically from World War II and Korean War era fighter planes. There are accounts of WWII pilots getting cancer from faulty compasses. I'm not saying that they are extremely dangerous and you should throw them away or avoid buying them, but you probably shouldn't handle or be around one constantly.

What features of the earth makes a compass needle point north
Iron can make a compass go haywire as it can create magnetic interference. When a compass is near iron or magnetic objects, it can disrupt the Earth's magnetic field that the compass relies on for accurate readings.

People use magnetic north as a reference point for navigation using a compass because the Earth's magnetic field causes the needle of a compass to align with the magnetic north pole. This makes it easier to determine directions when traveling.

Radioactive
A lensatic compass is a compass with a magnifying glass on the sight which makes it easier to view the needle. These types of compasses are frequently used in the military.
The AXIUM hand bearing compass is manufactured by Delite ApS, Copenhagen, Denmark.
it makes life easier because it can show you the direction you are going in.

Transuranium elements are radioactive and unstable; the stability of a nucleus is a problem of nucleon physics.
Over 99.999% of argon is not radioactive. A trace of radioactive argon-39 can be found in nature, but it is not significant. Synthetic radioactive isotopes of argon exist, as they do for all elements.
The final product is not radioactive.
The difference is that technetium is radioactive.
Oxygen, under normal conditions, is non-radioactive. But there are traces of radioactive isotopes present which makes the oxygen slightly radioactive. Additionally, these isotopes have long half-lives, so the radiation given off will not be a lot within a period of time.
Magnetism. The compass aligns with the magnetic field of the Earth.
