High-density polyethylene (HDPE) is irradiated to moderate gamma doses 10, 20, 30, 40 and 50 kGy to carry out the study of change in its states. It is conducted by measuring resistivity and capacitance due to scissoring of chains; hence, immergence of various functional groups in the bulk of samples is irradiated to three doses 10, 30 and 40 kGy. Enhanced resistivity is found to follow sequential change as ρ_10kGy > ρ_30kGy > ρ_40kGy > ρ_pris. Fractional change of resistivity, (ρ − ρ₀)/ρ₀, at small frequencies is correlated with fractional change of volume which is measured using the positron annihilation lifetime spectroscopy to estimate index of disorder, X. Disorder index, X, is the highest in the case of sample irradiated to 10 kGy gamma dose. Electrical capacitance, C, measured across the bulk of HDPE is found maximum in the case of 10 kGy dose, while samples irradiated to 30 and 40 kGy show capacitance smaller than the pristine HDPE indicating different dielectric behavior. Similarly, dissipation factor is found to be the smallest in the case of 10 kGy than 30 and 40 kGy doses up to several thousands of frequency in Hz. In all cases, electrical capacitance is found to be sustainable at high frequencies in the pristine as well as samples irradiated to the 10, 30 and 40 kGy doses.

高密度聚乙烯（HDPE）受到中等伽玛剂量10、20、30、40和50 kGy的辐照，以研究其状态的变化。它是通过测量由于剪链引起的电阻率和电容来进行的；因此，将各种官能团浸入大量样品中的剂量分别为10、30和40 kGy。增强的电阻率被发现遵循顺序变化作为ρ _10kGy  >  ρ _30kGy  >  ρ _40kGy  >  ρ _PRIS。电阻率的分数变化，（ρ  -  ρ ₀）/ ρ ₀在小的频率与它是使用正电子湮没寿命谱来估计疾病的指标，测量的体积的分数变化相关X。在以10 kGy伽马剂量辐照的样品中，无序指数X最高。电容，C在10 kGy剂量的情况下，发现在大部分HDPE上测得的最大，而辐照到30和40 kGy的样品显示的电容小于原始HDPE，表明不同的介电性能。类似地，发现在10 kGy的情况下，耗散因数比30和40 kGy剂量的情况最小，频率高达数千赫兹。在所有情况下，发现原始电容以及以10、30和40 kGy剂量辐照的样品在高频下均具有可持续的电容。
