接下来是辐射区，其范围从核心表面到太阳半径的70%处，占太阳总体积的32%，总质量的48%。

Next is the radiative zone, which extends from the core to 70 percent of the way to the sun's surface, making up 32 percent of the sun's volume and 48 percent of its mass.

辐射强度由存在准费米能级差的体积的吸收率决定。

The emission intensity is given by the absorptance of the volume in which there is a difference of the quasi Fermi energies.

热释光剂量测量方法是一种新型的辐射监测方法。它具有体积小，灵敏度高，量程宽，稳定性和线性好等优点。

TLD dosimetry is one of the new radiative monitoring method, having many advantages like small volume, high sensitivity, wide range, good stability, linearity etc.
