Radiation alert!

In the wake of announcements that body scanners are to be used routinely in airports a television journalist today reported that there was concern over the risk of radiation. If passengers are really worried about radiation they would be well advised not to fly at all since flying increases exposure to cosmic radiation which can harm DNA and cause cancers. As one travels further from the surface of the earth the atmosphere becomes thinner and the magnetic field weaker and exposure to cosmic radiation increases. It is one of the major problems of space travel.
Thus, passengers flying at 30,000 feet in an aircraft confront a greater risk of harmful radiation than from an airport body scanner. The amount of radiation emitted by a scanner used for security purposes is negligible.
Perhaps people who have concerns should avoid areas of high natural radiation – Cornwall in the UK for example, or Yangjiang in China, Kerala in India, Guarapari in Brazil, or the area with the highest level of background radiation, Ramsar in Iran.
Doubtless the worries over body scanners will persist for as long as ill-informed reporters continue to make alarmist remarks.

Further to ‘Threat levels’ re: TEA

Barry replied to the original email:

As a point of historical fact, the British Government was so alarmed about the risk to morale over a lack of tea available to its Armed Forces at the outbreak of WW2 that it purchased the entire worldwide stock of tea.  It is also worth pointing out is that at its height the British, Empire and Commonwealth forces numbered twelve million  - perhaps it built to that strength to justify the tea purchase.

Barry's respondent replied: Also worthy of note is the service once offered (and maybe continues to be) by the India Tea Council advising on the best way to prepare tea. I contacted them some time ago to answer a dispute I was having with some northerner who reckoned that 'mashing' tea i.e. stirring it was the way to make the best cuppa. Now having been taught by a good naval man (my Dad) I wasn't having that and the ITC were able to confirm that you must never stir tea as it bruises the leaves! 1 - 0 to the good guys!!

Janice's input: tea leaves produce an infinitely superior pot of tea but I like my tea unstrained – the leaves are good to chew on! . . . and Earl Grey is very refreshing . . . especially with lemon! It's the bergamot that enhances and perfumes it so delicately.
