The neutron energy spectrum of a 241Am-Be(_,n) source was measured by means of a 3He spectrometer in the energy range from 100 keV to 11 MeV.

Interesting measuring with the alpha radiation sources. We have prepared the experiment with MX-10 Particle Camera (particle detector) that can detect alpha Solution for A 5.0 x 105 Bq 241Am alpha source is used in a smoke alarm. The device is arranged so that 15% of the decay alphas are detected. (a) What current… sealed source that is not shielded and encased within the housing of an instrument.

The alpha particles emitted by the Am-241 collide with the oxygen and nitrogen in air within the detector's ionization chamber to produce charged particles (ions). A low-level electric voltage applied across the chamber is used to collect these ions, causing a steady, small electric current to flow between two electrodes. Am-241 found in the environment is in the form of microscopic dust.

A new search for production of correlated pairs in the decay of (241)Am has been carried out deep underground at the Gran Sasso National Laboratory of the IN
We have developed MICROMEGAS (MICRO MEsh GASeous) detectors for detecting a particles emitted from an 241Am standard source.

H. Kluge,. Oct 20, 2020 Am-241 sources are both gamma rays and alpha particles emitters. They are applied in industrial gauging, including X-Ray fluorescence the full cathode area of the crystal with the uncollimated 241Am alpha-particle source and measuring the resultant pulse-height spectrum at a typical detector The surface barrier detector and the 241 Am alpha source are contained in the stainless steel vacuum chamber.

The primary alpha peak from a 241Am calibration source was centered in channel number 461 of a multichannel analyzer when the alpha particles were collimated to be perpendicular to the surface of a silicon junction detector. Americium-241 decays by alpha emission, with a by-product of gamma rays.

241Am (Americium) Americium is a man made radioactive isotope, and is commonly found in smoke detectors. The source is an alpha emitter, and in the decay process it also kicks out a gamma at 59.6KeV. This is a typical gamma spectrum from Americium, as you can see, the tall peak at 59.6 KeV is very obvious and over powers everything else, it also has a gamma at 26.3KeV which is sometimes visible to the left of the tall peak.

Americium-241 has been used as a portable source of both gamma rays and alpha particles for a number of medical and industrial uses. The 59.5409 keV gamma ray emissions from 241 Am in such sources can be used for indirect analysis of materials in radiography and X-ray fluorescence spectroscopy, as well as for quality control in fixed nuclear density gauges and nuclear densometers . The alpha particles emitted by the Am-241 collide with the oxygen and nitrogen in air within the detector's ionization chamber to produce charged particles (ions).
