There are three primay ways to limit exposure to radiation, and they are time, distance, and shielding. By decreasing the time you are exposed, you limit exposure. By increasing the distance between you and the source, you limit exposure. And by placing shielding between you and the source you limit exposure.
Lead, solid rock, or a great depth of sea water. Ideally a barrier of concrete and lead is used for shielding from gamma sources.

Three factors affect radiation exposure- time, distance,, shielding. Time can be controlled in some cases by planning work in advance to limit the time you are exposed. Distance is frequently the best control- since exposure is based on the inverse square of the distance. Stay as far from the source as possible. Shielding is effective, however, is often not practical. Enough lead and concrete CAN stop most gamma rays- but you cannot walk wearing a ton of lead and concrete.
No, Tyvek is not a good gamma ray blocker. We know that Tyvek is HDPE (high-density polyethylene), and KDPE is a hydrocarbon. Even though it is "high density" material, it is only high density compared to other poly plastics. The best gamma ray blockers are materials with high mass. Atoms with high atomic numbers and high density are the ones we need to block gamma rays. Carbon and hydrogen don't fit the bill. Tyvek is a poor choice for gamma ray shielding. What is a good choice for gamma ray shielding? We might choose lead 'cause it's cheap and easy to use as well as a good gamma blocker. Certainly concrete and dirt work fairly well as we can get a lot of that stuff together to provide gamma shielding.
