Spectra of X- and g-rays emitted by the radioactive sources 241Am, 109Cd, 133Ba and 152Eu, with activities between 104 and 105 Bq, have been measured .

X-Ray Spectrum5.Types of The x-ray spectrum is defined as the energy distribution of the radiation produced in an x-ray exposure. The x-ray spectrum has a major impact on image quality and radiation dose delivered to patients. The authors explored the effects of three key factors on x-ray … characteristics x- ray line spectrum : When the target of an X-ray tube is stuck by energetic electrons, it emits two kinds of X-ray radiation. One of then has a continuous spectrum whose intensity distribution in wavelength depends entirely on the tube voltage. A REMARKABLE change in the X-ray spectrum of the transient source A0620-00 (ref.

Once in the body, it tends to concentrate in the bone, liver, and muscle. A method to perform the measurement of photon beam spectra from X-ray tubes is described.

The elements investigated were used as targets in x-ray tubes and the radiation from each target was analyzed with the aid of a single crystal spectrometer. A potassium ferrocyanide crystal was mounted on the spectrometer table and the spectrum was recorded on a photographic plate.

High quality spectra have been taken in the 0.1-2.4 keV energy range. The spectra from both observations are significantly steeper than those generally found in the 2-20 keV range The X-ray source 2U 1957+40 is shown from observations with the Copernicus X-ray instrument to be associated with the powerful radiogalaxy Cygnus A. The angular size of the source is found to be less than 10' arc, the resolution of the telescopes for these observations. The spectrum can be fitted by a power law of slope I 3 + or by thermal bremsstrahlung at a temperature >5 keV.

Ba133 Gamma Spectrum 133Ba (Barium) There are 33 known isotopes of Barium, of which 133Ba is the most stable, it has a half life of 10.5 years, and emits a whole range of gammas, some which can be readily identified with a sodium iodide detector, and many that require higher resolution to see.
