They can be. Some radioactive elements are chemical poisons, apart from their radioactivity, but beyond some fairly low level, the radiation itself can damage cells and tissues. High radiation doses can cause biological tissues (that's US!) to break down fairly quickly causing rapid death, and moderate radiation doses can cause cancers which can kill you over longer time periods.
Low doses of radiation are probably harmless; the level of "low" is a matter of some dispute among scientists and doctors.
Radioactivity can be harmful if living things are exposed to it for prolonged periods of time. There are many useful things that radioactivity does for us, particularly in the fields of medicne and in energy generation and production. But we don't want to be around unstable radionuclides for any length of time if we have a choice.
Radioactivity is the particles and/or energy emissions from unstable atomic nuclei, and these emissions are considered ionizing radiation. They can cause tissue damage, and are generally best avoided.
This is a very broad question. Radioactivity is not one single thing. Different materials emit different forms of radiation and these can be harmful to varying degrees. Radiation causes damage by ionising the molecules and chemicals in tissue to change their structure and thus affect their function.
There are 3 types of radiation:
If you have a particular material in mind, then it would be best to try and find out what form of radiation it emits. It could be any of them or any combination of them as a material can emit more than 1 radiation. Then do a bit of research on the effects of that form of radiation. In general, exposure to a minor source for a short period of time should not be dangerous, but steps should always be taken to protect yourself from direct contact. Always limit the time of exposure, if possible cover exposed body parts, and take any other reasonable precautions.
Radioactive materials emit dangerous radiation; most of this will be blocked by a box of lead.
The term for implanting radioactive materials into tissues for treatment is called brachytherapy.
Being radioactive lawrencium is dangerous.
Some common materials used to contain nuclear materials include lead, steel, concrete, and specialized containers such as fuel rod assemblies or storage casks. These materials are chosen for their ability to shield against radiation and protect the environment and people from exposure to dangerous radioactive substances.
The amount of radioactive material in a package of radioactive materials is typically measured in Becquerels (Bq) or Curies (Ci). This information is provided on the label of the package by the manufacturer or supplier. It is important to follow safety guidelines and regulations when handling radioactive materials to prevent exposure and harm.
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.
Radioactive materials emit dangerous radiation; most of this will be blocked by a box of lead.
yeah! almost all radioactive materials are dangerous, from these material radioactive rays are originated which are namely alpha,beta,gamma and when these rays strike to the body so it leave incurable burn,however its small amount is also harmful such as: the radioactive material named radium are found in varieties of wrist watches so its also harmful for human health X-Rays are electromagnetic rays and these are also harmful but not so much therefore physicians avoids for X-rays reports but in severe condition they are compel to do that advise There are two type of radioactive element one is natural radioactive and other is artificial radioactive element From natural radioactive element radioactive rays are always originated so,radioactive materials are dangerous even it is artificial or natural
In that case, the radioactive materials will pollute the atmosphere.
Radioactive materials contain unstable atoms that decay and emit radiation, while non-radioactive materials do not emit radiation. Radioactive materials can be harmful to living organisms due to their ionizing radiation, whereas non-radioactive materials are generally considered safe for everyday use.
Radioactive materials decay at predictable rates
Hazard Class 7 is the class for radioactive materials.
It is an area that is contaminated with radioactive materials.
What type of reaction produces the most dangerous radioactive waste?
No, some radioactive materials are not solids. Most radioactive materials are solids (uranium, plutonium, isotopes of many other materials) Some radioactive materials are gases (Radon) or isotopes of gases (Tritium, carbon fourteen, etc.)
dangerous goods These are goods that can be harmful to the environment if not properly handled or transported. Workers handling these dangerous materials such as radioactive, flammable, explosive, corrosive, oxidizing, asphyxiating, biohazardous, toxic, pathogenic, or allergenic substances must undertake certified safety training such as (TDG) Transportation of Dangerous Goods or (WHMIS) Workplace Hazardous Materials Information System in accordance with Canada Safety Regulations.
Radiation therapists have a potentially dangerous job since they work with radioactive materials, however, there are numerous safety procedures, and if followed correctly, the job is not particularly dangerous. The median yearly salary for a radiation therapist in the U.S. is $74,813.
