Is polonium alpha source?
Po is an alpha emitter that has a half-life of 138.376 days; it decays directly to stable 206Pb. The majority of the time, 210Po decays by emission of an alpha particle only, not by emission of an alpha particle and a gamma ray; about one in 100,000 decays results in the emission of a gamma ray.
What is alpha polonium?
Characteristics. 210. Po is an alpha emitter that has a half-life of 138.4 days; it decays directly to its stable daughter isotope, 206Pb. A milligram (5 curies) of 210Po emits about as many alpha particles per second as 5 grams of 226Ra.

What is the half-life of polonium-218?
The half-life of polonium-218 is 3.0 minutes.
What type of radiation does polonium-210 emit?
alpha particles
Po-210 emits alpha particles, which carry high amounts of energy that can damage or destroy genetic material in cells inside the body.
When polonium 218 decays it emits a beta particle followed by an alpha particle The resulting isotope is?
Lead-214
When polonium-218 decays, it emits a beta particle followed by an alpha particle. The resulting isotope is: A Lead-214.
When 218 84 Po emits a beta particle it transforms into a new element?
The atomic mass number is 257. The name of the element is Rutherfordium. When a nucleus of 218-84Po emits a beta particle, it transforms into the nucleus of a different element.
How many protons does polonium 218 have?
polonium (pəlōˈnēəm), radioactive chemical element; symbol Po; at. no. 84; mass no.
What is the alpha decay of polonium-210?
lead-206
Thus polonium-210 (mass number 210 and atomic number 84, i.e., a nucleus with 84 protons) decays by alpha emission to lead-206 (atomic number 82).
Is polonium-210 an alpha emitter?
Polonium-210 is a health hazard only if it is taken into the body. External exposure is not a concern because polonium is an alpha emitter. Alpha emitters can be very biologically effective internally but are hardly able to pass through a few centimeters of air outside the body.
What particle is produced when a polonium 218 atom undergoes alpha decay?
The decay of radon into polonium 218 is followed by further alpha decay into lead 214.
What is the daughter element in the nuclear transformation of 218 84 Po?
In alpha decay, an unstable nucleus will emit an alpha particle, which is a helium nucleus composed of two protons and neutrons. The mass number of the daughter isotope will be reduced by four, and the atomic number will be reduced by 2. The alpha decay of 21884Po produces 21482Pb .
When polonium-218 decays it emits a beta particle followed by an alpha particle The resulting isotope is?
What type of radiation is polonium-210?
When polonium-218 decays it emits a alpha particle followed by an beta particle The resulting isotope is?
