No, it is not safe to continue driving with worn brake pads and brake discs. Worn brake pads and discs can reduce the effectiveness of the braking system, leading to longer stopping distances and potentially causing a dangerous situation on the road. It is important to replace worn brake pads and discs promptly to ensure the safety of yourself and others on the road. **

Yes, a TÜV inspector does check brake pads and brake discs during a vehicle inspection. The inspector will visually inspect the brake pads and discs for wear and damage, and may also measure the thickness of the brake pads and the condition of the brake discs. This is an important part of the inspection to ensure that the vehicle's braking system is in good working condition and meets safety standards. If any issues are found with the brake pads or discs, the inspector will advise the vehicle owner to have them replaced. **

The need to replace brake discs and brake pads depends on their condition. If the brake pads are worn down to a thickness of 3mm or less, or if the brake discs are warped, scored, or have a thickness below the manufacturer's recommended minimum, then they should be replaced. Additionally, if there are any signs of brake pulsation, squealing, or grinding, it may indicate the need for replacement. It is important to have a professional mechanic inspect the brakes to determine if replacement is necessary for safe and efficient braking. **

You can buy radioactive minerals or stones from specialized online retailers that cater to collectors and enthusiasts of radioactive materials. These retailers often have a variety of radioactive minerals and stones available for purchase, along with information about their radioactivity levels and safety precautions. It's important to research and understand the potential risks and regulations associated with owning and handling radioactive materials before making a purchase. **

Gold is not radioactive. It is a stable element with a half-life longer than the age of the universe, meaning it does not undergo radioactive decay. This is why gold is often used in jewelry and other applications where stability and durability are important. **

Some meteorites can contain radioactive elements, such as uranium and thorium, which can emit radiation. However, the level of radioactivity in meteorites is generally very low and not considered to be a significant health risk. In fact, the amount of radiation emitted by a typical meteorite is often comparable to the background radiation that we are exposed to on a daily basis. Therefore, while some meteorites may be slightly radioactive, they are not considered to be highly hazardous. **

Yes, Wismut is radioactive. It is a radioactive element with the atomic number 83 and is also known as bismuth. It has a half-life of over a billion times the current estimated age of the universe, making it a very stable radioactive element. Wismut is commonly used in various medical and industrial applications due to its radioactive properties. **

Ruhla itself is not inherently radioactive. However, like many places around the world, there may be naturally occurring radioactive elements in the environment. It is always important to be aware of any potential sources of radiation and take necessary precautions to minimize exposure. **
