It depends on the nature and amount of radiation you want shielding from.
total cost ÷ square footage
What are excavations cost per square foot?
Multiply by 1.19599
cost of per square yard will be 468.00.

While gold is a common material used for shielding against gamma radiation due to its high density, it is not necessarily the best option. Lead is often considered a more effective and cost-efficient shielding material for gamma radiation due to its higher attenuation properties. Additionally, other materials such as tungsten and depleted uranium can also provide effective shielding against gamma radiation.
Steel and lead are both commonly used materials for radiation shielding, but they have different properties that affect their effectiveness and practicality. Lead is more effective at blocking radiation due to its higher density, but it is also heavier and more expensive than steel. Steel is less effective at blocking radiation compared to lead, but it is lighter and more cost-effective, making it a practical choice for certain applications where weight and cost are important factors. Ultimately, the choice between steel and lead radiation shielding depends on the specific requirements of the shielding application.

Shielding is the use of materials to absorb free or loose radiation, and prevent it from leaving the reactor; this would be a hazard to workers otherwise. The standard materials are concrete and lead, for their ease of use and installment, low cost and high effectiveness.
Because lead is a heavy element with a large atomic nucleus, it is effective at absorbing radiation; in addition, it's quite affordable (as compared to using gold, for example, which is also a heavy element).
The cost of a commercial air conditioner for a 5000 square food building can easily cost more than 7,000 dollars. Such models would normally go through the ceiling into other parts of the building.

That would totally depend on your definition of restoration.
Yes ceiling fans with lights worth the cost becasue you can use them to get cool and reduce your air conditioning cost and you can use the light or not to lighten up a room
Your installer's hourly charge will probably range from $20 to $40 an hour. The quote will estimate the number of hours required to tear down the old ceiling, prep the area and install the tiles.
There are many kinds of outdoor ceiling fans the prices vary from 143.00 to 340.00 http://www.ceilingfansbuy.com/outdoor/outdoor-ceiling-fans/
Depending on the pot rack and your location, to have a ceiling pot rack installed would cost around $200. If any electrical work is required, it would cost more.
