Variable Lead Thickness
The important balance in radiation protection is always balancing the radiation dose received and how much shielding is employed. While it is desirable for as much radiation shielding as possible and therefore allowing the minimum exposure to radiation, this is expensive, heavy and sometimes impractical.
The ability to store vials appropriately is pivotal in allowing usability while ensuring low radiation dose rates and ALARP. Other very practical considerations must be made such as the materials used - ensuring they don’t corrode – the total weight – ensuring they can be lifted and manipulated – the lid fixture – ensuring it stays on when required and comes off easily.
