“…1 and 2 agree with t'he values computed byMarshall (1955) within his stated uncertainty (&-yo for 3 points, f 2 % for 20 points). They also agree within about 2% with the curves ofMarinelli et al (1947) and Hine (1948): except for values of E, below about 0.3 MeV, for which their negatron curves are 5 t'o 10% high, and their positron curves . 5 to 10% low, as noted by Ma'rshall.…”

THE average P-particle energy per disintegration is a physical parameter of importance in the dosimetry of the radioisotopes, since the P-particle dose to biological materia'ls from a distribut'ed radioisotope source is proportional to this quantity. This paper presents the results of a systematic calculation of t'he ratio of average P-part'icle energy (E,) to the maximum P-particle energy (Eo), for the entire ranges of values of atomic number (2) and maximum P-part'icle energy which are likely to be of .biological importance. Values of E,;E', have been calculated for negatron spectra for the range Eo"O t o 4 xev and Z=O to 100, and for positron spectra for the range E0=0.2 t,o 4 BIev and Z=0 to 80.

The primary application of radiation shielding is to safeguard against the harmful effects of radiation. This study investigated the addition of thulium oxide (Tm2O3) to a glass system with a composition of 75 TeO2–5 Li2O–10 ZnO– (10-x)Nb2O5. Multiple radiationshielding parameters, including linear and mass attenuation coefficients, half-value layers, mean free paths, atomic and electronic cross-sections, effective atomic numbers, and effective electron density, were evaluated. The study compared the half-value layer values of the new composite to those of well-known radiation-shielding materials, which include ordinary concrete and commercial glass. The addition of Tm2O3 to glass systems efficiently increases the atomic and electronic cross-sections. While all samples had the greatest linear and attenuation coefficients of 201.5–232.84 cm2 /g at 15 keV, the denser glass had the highest mass attenuation coefficient of 42.80 cm2 /g. The shielding effectiveness depends on the phases structure of TeO2 occurred in the prepared glasses.
