How thick of lead to stop gamma
NettetAnswer (1 of 2): First, you want a thickness, not width and second it is x-ray energy not frequency. Yes there is a frequency for an energy, but nobody does calculations from frequency except a physicist. You specified lead but common steel or concrete blocks x-rays as well. You want the attenuat...

Did you know?
NettetHow good? Well, according to a report on the topic prepared for the DoE back in 1977, a layer of water 7 centimeters thick reduces the ionizing radiation (rays and particles) transmitted through it by half (the remainder is captured or moderated to non-ionizing energy levels, mainly heat). NettetThe various types of radiation - alpha, beta, gamma, neutron, and x-rays - differ chiefly in their ability to penetrate and ionize matter. It is the latter charac-teristic which injures living tissue and which must be guarded against. The alpha particle is a positively charged helium nucleus which is completely stopped
NettetA few inches of lead is enough to block gamma rays -- which is why you wear a lead apron when you get x-rays -- but at least 3 meters of concrete are needed to stop them. Again, the precise...

Nettet23. mar. 2024 · Most resources say that beta particles can be stopped by a one-quarter inch thick sheet of aluminum. Once again, however, the greatest danger occurs when the beta emitting source gets inside of you. Gamma rays are not particles but a high energy form of electromagnetic radiation (like x-rays except more powerful).
