It depends on its strength, type and the length of exposure. Most people will tell you Marie Curie discovered radiation, along with her husband and research partner Pierre. And that's right -- sort of. Curie actually discovered the element radium in 1898, an accomplishment that would make ...
In addition, at magnetic field strength of 0.35 T, Darafsheh et al. [30] and Xhaferllari et al. [31] didn’t notice any significant difference in the response of EBT3 film irradiated in the presence or absence of an external magnetic field. Absolute dose verification for beam output ...
Lead, which has been used for radiation shielding in medicine, is currently sought to be replaced by an eco-friendly shielding material. Therefore, it should be replaced with shielding materials possessing excellent processability and radiation shielding performance similar to that of lead. In this st...
The strength of this current is proportional to the number of ionization events caused by the energy absorbed in the air chamber and will serve as a measure for find the exposure rate or dose rate.Figure shows the circuit diagram of ion chamber based meters. ...
A limitation of this study is lacking data on postoperative complications, delaying RT, lymphovascular invasion, mitotic activity index and Her2 receptor status. Any differences in these factors or other unmeasured confounders among interval groups may have introduced confounding by severity. For the Her...
[29]. The strength of the Bragg peak degradation is quantified by the material characteristic “modulation power” Pmod: The greater the modulation power of a heterogeneous material like lung tissue the broader the Bragg peak and the less steep the distal fall-off as shown in Fig. 4. Based ...
[21]. In addition, a lifetime study by the Ramazzini Institute reported a significant increase in heart schwannomas in male rats exposed 19 hour/day to 1800 MHz GSM-modulated RFR at a field strength of 50 V/m, equivalent to a whole-body SAR of 0.1 W/kg [22]. The ...
摘要: PURPOSE: To obtain a wire and a cable which have an excellent heat-resisting and radiation-resisting property, a good flexibility, a good electric characteristics, a good mechanical strength, and can thin its outer diameter, and furthermore, has an excellent productivity....
The elastic modulus (EM), maximum strain (MS), and ultimate tensile strength (UTS) in the 20-Gy group were significantly weaker than those in the 0-Gy group. The EM and UTS in the 20-Gy group were significantly lower than those in the 10-Gy group. The UTS and MS in the 10-Gy ...
Imaging has an essential role in the planning and delivery of radiotherapy. Recent advances in imaging have led to the development of advanced radiotherapy techniques—including image-guided radiotherapy, intensity-modulated radiotherapy, stereotactic bo
