Radium

Rubidium has one stable isotope,85Rb. The isotope 87Rb which composes almost 28% of naturally occurring rubidium is slightly radioactive, with a half-life of 49 billion years-more than three times longer than the estimated age of the universe.

There are 26 isotopes of rubidium known with naturally occurring rubidium being composed of just two isotopes; Rb-85 (72.2%) and the radioactive Rb-87 (27.8%). Natural rubidium is radioactive with specific activity of about 670 Bq/g, enough to fog photographic film in approximately 30 to 60 days.

Rb-87 has a half-life of 4.88 × 1010 years.

Based on Wikipedia article on Rubidium.

Do not know

In July of 1898, Marie and Pierre Curie discovered polonium. Just five months later, in December of 1898, they went on to discover radium as well.

Reimbursement and Research

Simmons solid radium silver is a type of flatware or silverware that was manufactured by the Simmons Company in the early 20th century. It is known for its durability and distinctive design featuring radium detailing, which was a popular decorative element at the time. However, due to the radioactive properties of radium, it is important to handle and use Simmons solid radium silver with caution.

In mathematics, the term "radium" is not commonly used. Radium is a chemical element with the symbol Ra on the periodic table. It is a radioactive element with atomic number 88.

Today radium has only limited applications in research laboratories, for example for the preparation of radon standard solutions, in neutron sources of the type Ra-Be, etc.

Possible use in radiotherapy of some cancers.

Radium was used in the past for luminescent painting of watches and other instruments, was used in toothpaste, cosmetics, etc. These applications are not permitted now because radium is strongly radioactive and dangerous.

skin turned grayish, hurt, and he thought radium could be used in treating cancer. that was later proved after his death.

It isn't used for anything anymore--they have better, safer isotopes to do the things radium was once used for.

The mass number 228 isotope of radium has 88 protons and 140 neutrons. It is a radioactive element with a half-life of about 5.75 years, decaying into radon-220 through alpha decay. Radium-228 is used in medical treatments and research.

radium has NO odor

Just the facts, Radium stops canser in its tracks!

Before it was known how harmful the radiation emitted by radium as it decays is to living tissue, it was applied to some products such as watch faces for its glow-in-the-dark property. Now we know better. Today, unless you are working in the field of nuclear medicine or you are mining uranium ore, you will not be running into radium.

A new lipstick has been introduced in the market. They have used radium for the glowing effect. The cost of per lipstick is about 950 .Rs.

The name radium is derived from the Latin language word radius, equivalent to radiation.

From these isotopes decay products are obtained and also ionizing radiations.

Absolutely not.

While there are radioisotope batteries, radium is too expensive and dangerous for it to be used in them! Most radioisotope batteries use either plutonium-238 or tritium as the radiation source. It can be quite dangerous to handle these batteries. Radioisotope batteries can generate usable electricity for one or two halflives of the isotope and can thus function for years to centuries (or even longer) before going dead. Radioisotope batteries are almost always custom designed for the application and sometimes cannot be replaced as the device using them (e.g. deep space probe, equipment for operation in inaccessible remote sites) will not be operating at a location where any repairs or replacements would be practical.

Lithium batteries are chemical batteries, that generate electricity by electrochemical "corrosion" of plates inside the battery. Primary lithium batteries can go dead in weeks to months. Secondary lithium batteries may not go dead for years, but need to be recharged. Most lithium batteries are designed to be user replaceable.

Polonium is not used for the treatment of cancers.

Radium is used to treat bone cancers.

The isotope 192Ra don't exist.

The two isotopes used as tracers in pipelines are barium 140 and antimony 124
