None - any dosage has risks
Theoretically, one single molecule of a carcinogen can cause a cell to mutate and that to spread to other cells to cause cancer. (Oxygen is also a powerful mutagen!) However, this is multi-stage process, which is dependent on several other factors and the cells have defence mechanisms to combat this. Radiation is believed to somehow interfere in the chain of events.
In theory, there is no safe dose but then it goes down to probability theory. The human body itself produces several 'known human carcinogens' endogenously - ethanol, estrogen and testosterone, to name three. Sunlight is radiation (and moonlight is reflected sunlight!).
It's like saying there's no safe dose of lightning - but only if it strikes you and you're standing barefoot on a metal grill and you've got a weak heart. (There are around 100 lightning strikes per second globally!)

How can uv radiation make water safe?
I dont know the exact explanation but few days back i read in the newspaper that drinking RO or UV water lowers ones body's immunity...... I don't why or how/??? Just read it..... It is not a short term issue.. but a long term... i mean if such a speculation is true then it can only happen to that person whi has been drinking that water for many years... not to the one who has started drinking that water a month back......

Why was a chimpanzee sent into space in 1961?
To see if it was safe for a human to travel into safe. If the monkey made it, a human might survive space travel. If the ape died, then it was not safe for a human to go into space. The chimp lived, so human beings were sent into outer space.
Does The film badge keep radiation workers safe from radiation?
Not directly, but it allows them to monitor how much dose of radiation they have received over a period of time, so they can look at it and check they haven't received too much dosage.
Will baygon cockroach killer kill human beings?
Some products in an insectiCIDE killer contains MORE HAZARDOUS and DANGEROUS to human beings.

How is infrared dangerous?
They're not dangerous, on earth, because less amount of infra-red gets to us but sometimes it can give us tans, because sun radiation is infra-red and you can get sun burn, so you can say that it doesn't have much danger on human beings on earth, for in space you have to wear space suits and you have to have space shuttle to be safe on space, because space has far more dangerous infra-red radiation. so I would say that infra-red doesn't have much harm of humans beings on earth, but it is very harmful in space.
Gamma radiation is it safe to inject into a human but alpha particles would be very dangerous?
Generally no radiation is safe. You cannot "inject" radiation into anything because it is the product of various unstable nuclei decaying. Alpha radiation is much more ionising than gamma, but much less penetrating than it. That makes it more dangerous if it is inside your body; it can be stopped by skin. Therefore you would have to swallow a sample of a radioactive material. However, gamma radiation is always emitted together with alpha or beta radiation.
What is a safe amount of radiation?
Depends on the TYPE of radiation, how long you are exposed and the person being exposed. In the case of ionizing (nuclear) radiation, pregnant women and children have a lower safe level than other persons. For non-pregnant adults, 5,000 millirems per year is the maximum legal occupational exposure. However, the goal is always ALARA- a dose As Low As (is) Reasonably Achievable- meaning you do not expose a person for no reason. Other radiation- such as radio wave energy- has different levels. There is NO "safe" level that does not entail some risk of injury- just levels that are not found to be especially injurious.
