Yes. Intensity is an important factor in whether and where cancer develops. But not so much in the latency period, which is what we are talking about.
The point is that coming to a conclusion about the potential risk of these machines by comparing them to something similar isn't very scientific because too many variables are involved.

2 months is far to short of a period of time for cancer to develop.

What has been said is that because the levels of radiation produced by the machines is so low, it would be impossible to isolate the machines as the cause of any particular case of cancer.

Investigation of X-Ray Harmonics of the Polarized Inverse Compton Scattering Experiment at UCLA
An Inverse Compton Scattering (ICS) experiment, which will investigate nonlinear properties of scattering utilizing a terawatt CO2laser system with various polarizations, is ongoing at the UCLA Neptune Laboratory. When the normalized amplitude of the incident laser's vector potential a0is larger than unity the scattering occurs in the nonlinear region; therefore, higher harmonics are also produced.
There are two types of AIT machine commercially available, using either ionising or non-ionising radiation. The former involves backscatter X-rays and the latter involves tera-hertz electromagnetic radiation (which includes `millimetre wave' technologies).
Here are some simple facts:-

The backscatter machines are using high powered CO2 lasers and different polarizations to produce x-rays?
Interesting, seems pretty inefficient. I thought they used ordinary x-ray tubes.

You are misreading the statistic. It does not say that 10% of children exposed got cancer. It says that up to 10% of childhood cancers were caused by radiation. In 1977 (the year of the statistic) the childhood cancer rate in children (1-14) was 11.5 per 100,000. 10% of that is 1.1 per 100,000. In 1977 that would be 37 of the children born that year. That is not a lot of people.

TSA uses two types of scanners. One uses millimeter waves, the other x-rays. What is being discussed here is the x-ray backscatter machines (ionizing radiation).
The millimeter wave scanners operate at microwave frequencies, non-ionizing radiation. Gigahertz, not terahertz. Like a cell phone.

Phage didn't you say they werent using tera hertz scanners back there somewhere?
Millimeter or GHz scanners are often wrongly cited as emitting terahertz radiation. Currently adopted scanners operate in the millimeter or sub terahertz band. The use of terahertz radiation (between 1 and 10 THz) shows promise but is currently not commercially available for body scanning.

FOR IMMEDIATE RELEASE

All Levels of Radiation Confirmed to Cause Cancer.
Washington, DC July 30, 2005 The National Academies of Science released an over 700-page report yesterday on the risks from ionizing radiation. The BEIR VII or seventh Biological Effects of Ionizing Radiation report on "Health Risks from Exposure to Low Levels of Ionizing Radiation" reconfirmed the previous knowledge that there is no safe level of exposure to radiation—that even very low doses can cause cancer. Risks from low dose radiation are equal or greater than previously thought. The committee reviewed some additional ways that radiation causes damage to cells.
Among the reports conclusions are:
There is no safe level or threshold of ionizing radiation exposure.
The BEIR VII risk numbers indicate that about 1 in 100 members of the public would get cancer if exposed to 100 millirads (1milliGray) per year for a 70-year lifetime. [1] This is essentially the US Nuclear Regulatory Commission's allowable radiation dose for members of the public.
In addition, 1 in about 5 workers [2] would get cancer if exposed to the legally allowable occupational doses [3] over their 50 years in the workforce. These risks are much higher than permitted for other carcinogens.
Specifically, the US Nuclear Regulatory Commission allows members of the public to get 100 millirems or mr (1 milliSievert or mSv) per year of radiation in addition to background. The BEIR VII report (page 500, Table 12-9) estimates that this level will result in approximately 1 (1.142) cancer in every 100 people exposed at 100 mr/yr which includes 1 fatal cancer in every 175 people so exposed (5.7 in 1000).[4]
The risk of getting cancer from radiation (in BEIR VII) is increased by about a third from current government risk figures (FGR13): BEIR VII estimates that 11.42 people will get cancer if 10,000 are each exposed to a rem (1,000 millirems or 10 mSv). The US Environmental Protection Agency Federal Guidance Report 13 estimates that 8.46 people will get cancer if 10,000 are each exposed to a rem.
