I have questions about uranium and autism?

My grandfather died at age 60 from spider cancer. He was employed at Simmons Steel Plant in Lockport,NY, in the 1940's and 50's. He worked with radioactive materials used for warfare,uranium and thorium. My question is can these materials affect dna, and can that damage be passed along from generation to generation? My brother has Aspergers. My oldest son has PDD-NOS and my 2 yr.old is showing signs of ASD also. Thanks.I have questions about uranium and autism?
Absolutely, but not quite the way your thinking. For example, thousands have been recovered from autism, my children included. It's done by treating for pathogens and toxins. Mothers do pass toxins and pathogens into her children. The father passes pathogens as well on his sperm and via contact and such when the child is born. What is being found is that toxins create an immune state where pathogens live in people in a chronic manner. So, instead of getting a fever and very sick when they get Bartonella from a cat scratch or flea bite, they get chronic Bartonella since Bartonella is a pleomorphic, immune-suppressing pathogen. These people will have symptoms of just about every thing you can imagine, but usually they have OCD-type symptoms where they need to have things a certain way. Anyhow, due to their toxin load, they will not fight off the Bartonella, nor get ill when they get infected. But, years later, their immune system will tire, and other pathogens and toxins will stock-pile and more chronic symptoms will develop. Achy feet and anxiety are other symptoms commonly seen in Bartonella. All the children and spouses will be exposed now to this Bartonella infection this person has. So, you see, it's more the fact that your grandfather had toxins causing suppressed immunity, causing him to be a carrier of the many pathogens he came into contact with. On this note, let me add that Zithromax is probably the number one thing given to those with autism by doctors who are recovering children with autism. Zithromax kills Bartonella, Strep, Babesia, Lyme and other pathogens being found to be stock-piled in these children. Their immune systems are inadequate due to such immune-suppressing pathogens and toxins, and other stresses, such as electrosmog, vaccines, molds, poor quality of food nowadays (pesticides, etc.). There is much to learn. See www.heidinotes.com for what I learned.
