All radioactive materials can enter your body one way or another. For example, urainium decays exteamly slowly, having a half life of some four billion years. Therefore it's radiation is very weak and cannot penetrate human flesh, however, it can still be inhaled.Potassium40 is possibly the most common radioactive material that enters your body- it is well coupled to ordinary potassium, and apparently does no great harm. C14 would be another one.these are known as cosmogenic nuclides, because they are made radioactive by hard radiation from space. (Q does K40 belong to the group?)
If you are talking about the geological stone called marble then no it is not. If you are referring to the little stone or glass balls used in games then some of them are a little radioactive. If you have glass marbles you can check this by shining a black light on them. If they glow they have a little radioactivity in them. Not that it is enough to harm anyone. Anything that glows in the dark is radioactive.
Yes. Radium is a radioactive element that is found in small amounts in uranium ores. Radium, like all other radioactive materials, is dangerous if handled improperly. It was most famously used in luminescent paints. There was a lawsuit filed against their employers by five dying women who, uneducated about the dangers of radioactive Radium, were hired to use the paints to make the faces of glow-in-the-dark watch faces for the military. The radium in the paint seeped through their skin into their bodie and they suffered from bone cancer and anemia. Radium, once in the body, is treated as calcium and transfered to the bones where its radioactivity degrades the marrow, reducing blood production and possibly mutating bone cells.
Dry paper is easy to ignite unless it is especially treated to be fire-resistant. Wooden match sticks light easily.
Adhesion of muscle cells to cells of non-muscle tissues would be disrupted.

Brachytheraphy
The most general term is "radiotherapy", or "radiation therapy", but that term would also include external sources of radiation being used to irradiate the target tissue. When radioactive sources are implanted to deliver a therapeutic dose of radiation, the term "brachytherapy" is used.

Basically, radioactive iodine is used to kill cancer cells, and thyroid tissue.
Europium is radioactive, though for most practical purposes it can be treated as stable. 52.2% of europium is stable. 47.8%, is radioactive 151Eu, but the half life of this is long, at 5,000,000,000,000,000,000 years. Like all other elements, europium has radioactive synthetic isotopes.
Addison's disease is treated using the oral administration of radioactive iodine to destroy thyroid cells.
The healthy spouse may suffer symptoms of and need to be treated for hypOthyroidism.
Viva tissues, like most other paper products, are made from wood pulp. Tissues are specially treated to make them softer on the skin.

He was being treated with radioactive iodine for Graves' disease.
