The name for the emissions of rays and particles by a radioactive material are called radioactive decay. There are many different types of radioactive decay that emit different rays and particles.
Negatively charged particles are called electrons, positively charge particles are called protons. Particles without charge are called neutrons.
Yes, protons and neutrons.
A Phase Change
A magnet can pick up tiny iron particles that are in sand.
Light, flexible material, can be drawn into fibers and it takes dies well.

The DOT (Department of Transportation) class for radioactive materials is Hazardous. The specific Hazard number will be determined by the exact name of the radioactive materials. Special permits and placarding are needed for vehicles carrying hazardous materials. The DOT class is categorized into 9 classes according to hazardous materials transportation. Class 7 is the general DOT class for radioactive materials.
1. put it in a lead box 2. move it further away
Radium got its name from the Latin word radius, meaning ray. The early studies of radioactive elements (by Pierre and Marie Curie and others) found that their photographic effects were similar to that of light rays. Scientists categorized the "rays" given off by radioactive elements by their reaction with magnetic fields. Eventually the positive "rays" were named as Alpha particles (helium nuclei). Beta particles were negatively charged (electrons), and Gamma rays had no charge.
This usually called the Law of Conservation of Matter, or sometimes the Law of Conservation of Mass. It applies to ordinary chemical reactions and physical changes, but not to radioactive materials.
Thorium is a radioactive metal.
the material on the moon is typically called moon dust but I am not sure what the official name is. it consisted of smooth particles not found on the earth's surface.
Radioactive Man
Well, to start with, that is a provisional name, and not the final name. It is a man made substance that does not exist in nature, only about 100 atoms of it have ever been made, it is radioactive, and very unstable- it changes to another material in a fraction of a second.
