Radium
* also dissolves in water.
* bright silver radioactive metal that darkens upon exposure to air.
* combines with most non-metals, including oxygen, fluorine, chlorine, and nitrogen.
* decay product of uranium.
* emits a , b , and g rays and when mixed with beryllium produces neutrons.
* gets into the water because of pollution from fertilizer and lime used on the land.
* gives birth to radon, an odorless, colorless gas that is linked to lung cancer.
* has no biological role.
* is about one million times more active than uranium
  - chemical elements
  - dangerous when ingested
  - found in all uranium minerals
* is found in soil, rocks, and certain building materials
  - water, plants, and food at low concentrations
  - uranium and thorium ores
  - naturally
  - highly radioactive and hence carcinogenic
  - in the same chemical family as Calcium, so has similar solubility and reactions
  - incorporated into the chimneys and can be used to determine source and age
  - intensely radioactive
* is known to cause bone cancer if consumed in high doses
  - when consumed in high doses
  - have caused health problems for persons who ingested it for long periods of time
  - metallic elements
  - naturally present in the environment in very small amounts
  - over a million times more radioactive than the same mass of uranium
  - present at very low concentrations in sea water
* is present in all uranium minerals and is widely distributed in small amounts
  - low concentrations in most soils and rocks
  - trace amounts in all rock and soil
* is radioactive and very slowly decays
  - substances
  - the heaviest of the alkaline-earth metals
  - used as a portable source of neutron radiation in medicine and industry
* is used in cancer therapy and luminescent paint
  - luminous paint
  - to produce radon , a radioactive gas used to treat some types of cancer
  - widespread in shallow wells throughout southern New Jersey
* known cause of bone and nasal cancers
  - nasal and bone cancers
* lustrous white radioactive metal.
* metal that is found in nature.
* metallic element which occurs naturally within the ground.
* naturally occurring element distributed throughout the earth s crust in varying amounts.
* occurs naturally as uranium decays - though only in very small quantities.
* produces radon, a radioactive gas whose decay products can cause lung cancer.
* radiological hazard.
* rare metal.
* silvery-white metal.
* very rare radioactive material.

Supramolecular chemistry
* is also important to the development of new drug therapies.
+ Supramolecular chemistry, Uses, Medicine: Chemistry
  * Supramolecular chemistry is also important to the development of new drug therapies. Supramolecular chemists study the interactions at a drug binding site. The area of drug delivery has also made critical advances as a result of supramolecular chemistry providing encapsulation and targeted release mechanisms. In addition, supramolecular systems have been designed to disrupt protein-protein interactions that are important to cellular function.

Surface chemistry
* Most surface chemistry happens in or on monolayers.
* explores the forces at work on membrane edges.
* is chemistry
  - highly sensitive to the presence of contaminants on the surface of interest
* plays an important role in the cure of the classic cyanoacrylate adhesives.

Thermochemistry
* Thermochemistries are chemistry.
* deals with energy, heat and work.
* is about measuring the energy difference between the initial and final states

Chiropractic science
* focuses on the relationship between the spinal column and the nervous system.
* teaches that the health of the spine is essential to the health of the body.
