Irradiation Shield 1" for mice <25g

The shields are not suitable for 360 degree irradiation (typical of a Cs source), and they are limited for use in units that produce energies less than 350kVp (X-Ray). The fixtures are to be used with fixed beam X-ray sources projecting vertically and do not protect the exit side of the irradiated specimen. A shield designed for use with a Cs source typically requires 4 times the lead thickness. These shields are ¼" (6.35mm) lead, and the attenuation factor depends on the kVp energy they are used with. Attempts to use our shields with a Cs source will result in inadequate shielding and overexposure to protected areas of an animal. The shields are regularly used in the Orthovoltage energy range (<320 kVp) and provide about a 100X attenuation. See Attenuation Curves for a better evaluation.

Braintree避难所小屋II 一个舒适，安静的地方休息，或爬上去探索。切碎的材料（只是为了娱乐或筑巢），通常需要7至30天。直径4英寸x高2英寸，带有3个大窗户和更宽的门，可提供更安全的出入口。较大的孔还使工作人员可以轻松地将垃圾放在庇护所内，以观察它们。
