The ASTAR program calculates stopping power and range tables for helium ions in various materials. Select a material and enter the desired energies or use the default energies. Energies are specified in MeV, and must be in the range from . 01 MeV to 1000 MeV

The ASTAR program calculates stopping power and range tables for helium ions in various materials. 01 MeV to 1000 MeV. Also the effect of radiation on different human parts like skin, bone, muscle, skeletal, adipose tissue, and water, where studied using these codes by calculating the stopping power and range on these different target, also dose can be easily calculating from stopping power

CSDA range, stopping power and mean penetration depth energy relationships in some hydrocarbons and biologic materials for 10 eV to 100 MeV with the modified Rohrlich–Carlson model. An interesting result is that the Montenegro et al. formula produces results better than its corrected version; the Öztürk et al. relation, despite the range and range straggling calculations indicating that the produced results by using the Öztürk et al. formulation are better than the Montenegro et al. formula when compared with experiment.

Electronic stopping power of compounds was calculated by using TFDW . Phase effects depend on the type of material. The effective charge of energetic ions as it pertains to the stopping power of solids is calculated in a dielectric-response approximation.

Electronic stopping power of compounds was calculated by using TFDW density functional. Bragg’s rule was employed to determine stopping power of compounds from the elemental stopping power results. For H2O and organic materials, stopping cross-sections are larger in the vapour phase than in the condensed phase by up to ~ 5-10% at stopping power maximum for H and He ions. At lower energies, the situation is still uncertain.

Electronic stopping power of various organic compounds for proton (. 5-10 MeV) calculated using . The accurate dosimetry of proton radiation depends on a detailed knowledge of proton stopping power in the material of interest. 5-10 MeV) calculated using different theoretical and semi-empirical formulations has been analysed in the present investigation. The stopping power values calculated using Ashley’s dielectric model (ADM) with evaluation approach for optical energy loss function (OELF) have been compared with the values computed using the theoretical formulation CasP (Convolution approximation for swift Particles) and semi-empirical approach SRIM (Stopping and Range of Ions in Matter).

The P value or calculated probability is the estimated probability of rejecting .

The P value or calculated probability is the estimated probability of rejecting the null hypothesis (H0) of a study question when that hypothesis is true. Most authors refer to statistically significant as P < . 5 and statistically highly significant as P < . 01 (less than one in a thousand chance of being wrong). The asterisk system avoids the woolly term "significant". The following table shows the relationship between power and error in hypothesis testing

The derived stopping power and energy. Note that in all the energy loss straggling calculations the input data used for the H, C, N and O constituent elements of the kapton target, reported in Ta., were taken from the ICRU-73 report. As can be seen in Fig. 2, our ? experimental results are in fairly good agreement with both previous data from reference and the ICRU-49 report over the common explored proton energy ranges. They are also in excellent agreement with experimental data from references for 1100 keV.

Stopping cross sections of TiO2 films were measured for H and He ions in the energy intervals 200−1500 keV and 250−3000 keV, respectively, using the Rutherford backscattering technique more. Stopping power calculations of He ions in Al and Zn are presented, including the electron-electron contribution mentioned above more. Energy-loss measurements and theoretical calculations for Be and B ions in Zn are presented.
