U-236 undergoes alpha decay. Alpha radiation has such a low penetration power that your bare dead surface skin is usually enough to block the radiation from causing you harm. You have to ingest the material for it to be a radiation risk.

The only thing I know of that has a kill time close to 5 minutes is the elephant's foot in the Chernobyl reactor building, certainly nothing close to a hospital. Shortly after the time of its formation the highest contributors to its radioactivity were a lot of isotopes with shorter half lifes, typically under 30 years. That lump has already lost over half it's radioactivity from it's formation.

Thyroid cancer in these individuals is caused by iodine-131 that was absorbed by the thyroid shortly after the Chernobyl incident. Anyone who is wearing a Chernobyl necklace was exposed to fallout within mostly the first eight days after the incident or to put it another way anyone who was in the area of fallout after May 5th, 1986 is unlikely to wear one.

Your statement is rather pointless as it does nothing to refute his point regarding long term habitation in the area post accident.

I personally only consider the first one a cure. Under the second definition you are still negatively impacted by the disease which is, to me, a perversion of the term cure. You may not be at risk of death or injury from the disease but your life is still negatively impacted by the disease by requiring you to upkeep treatment in order to avoid the death or injury.

The radiation therapy for the blood cancer kills off most of the marrow cells but not all of them. The remaining living cells could still harbor the HIV virus. They were unsure if the HIV was eradicated because the donation occurred and the donor's T-cells attacked the hosts marrow eradicating hiding places for HIV or if it was because the donor's T-Cell were mutated in a way that made them resistant to HIV. The radiation played a part but undoubtedly the transplant was the reason for it.

While it is a treatment that has cured someone of HIV. I don't personally consider it a cure because you're just removing the diseased region. For comparison, if I had skin cancer on my left forearm I'm not "cured" of it if I amputate my left arm.

It's great that this guy is cured of HIV but they need to find out if it was a mutation in the donor or the donation itself and even then it's not a cure as long as it's reliant on donors because the number of people that can be cured is going to be smaller than the total pool of HIV infected individuals. We need to be able to synthesize the cure so that it can be distributed to most of the victims.

We have not found a cure for either. What we have found is more effective treatments that reduce the rate of mortality. Earlier detection of cancers allows doctors and surgeons to treat and operate on cancers before they have time to grow and spread. We can get to a point where we no longer detect cancerous cells in your body but you are by no means cured because the detection is not absolute.

Treatments for HIV has helped many people avoid having it develop into AIDS but we haven't cured HIV. The people going through treatments still have HIV and are still at risk of it developing into AIDS.

It's a very loose definition of military operations. A significant number of these operations are evacuation or rescue of US civilians and personnel or troops sent to guard US property, such as embassies.

I was particularly amused by the one that was three cargo planes with crew sent to Congo to support them as they needed.

They're used for breaching buildings and rooms. They're a lot cheaper than using lives or grenades to figure out if the room/building is empty or not. A shotgun only needs to be aimed in the general direction of the target while a rifle needs to be aimed at the target in a way that will hit the target so that he goes down. A shotgun doesn't require as much reaction speed or precision as a rifle in order to safely breach a room.
